.SH DESCRIPTION
.B dgit
-treats the Debian archive as a version control system, and
-bidirectionally gateways between the archive and git. The git view of
-the package can contain the usual upstream git history, and will be
-augmented by commits representing uploads done by other developers not
-using dgit. This git history is stored in a canonical location known
-as
-.B dgit-repos
-which lives outside the Debian archive (currently, on Alioth).
-
-.B dgit clone
+allows you to treats the Debian archive as if it were a git
+repository. See \fBdgit\fP(7) for detailed information about the data
+model, common problems likely to arise with certain kinds of package,
+etc.
+
+The usual workflow is:
+.br
+1. \fBdgit clone\fR or \fBfetch\fR;
+.br
+2. make, do dev tests, and commit changes in git as desired;
+.br
+3. build packages for upload, using e.g. \fBdgit sbuild\fR
+.br
+4. do pre-upload tests of the proposed upload;
+.br
+5. \fBdgit push\fR.
+.SH OPERATIONS
+.TP
+\fBdgit clone\fR \fIpackage\fP [\fIsuite\fP] [\fB./\fP\fIdir|\fB/\fP\fIdir\fR]
+Consults the archive and dgit-repos to construct the git view of
+history for
+.I package
+in
+.I suite
+.RB ( sid
+by default)
+in a new directory (named
+.BI ./ package
+by default);
+also, downloads any necessary orig tarballs.
+
+The suite's git tip is
+left on the local branch
+.BI dgit/ suite
+ready for work, and on the corresponding dgit remote tracking branch.
+The
+.B origin
+remote will be set up to point to the package's dgit-repos tree
+for the distro to which
+.I suite
+belongs.
+
+For your convenience, the
+.B vcs-git
+remote will be set up from the package's Vcs-Git field, if there is
+one - but note that in the general case the history found there may be
+different to or even disjoint from dgit's view.
+.TP
+\fBdgit fetch\fR [\fIsuite\fP]
+Consults the archive and git-repos to update the git view of
+history for a specific suite (and downloads any necessary orig
+tarballs), and updates the remote tracking branch
+.BR remotes/dgit/dgit/ \fIsuite\fR.
+If the current branch is
+.BI dgit/ suite
+then dgit fetch defaults to
+.IR suite ;
+otherwise it parses debian/changelog and uses the suite specified
+there.
+.TP
+\fBdgit pull\fR [\fIsuite\fP]
+Does dgit fetch, and then merges the new head of the remote tracking
+branch
+.BI remotes/dgit/dgit/ suite
+into the current branch.
+.TP
+\fBdgit build\fR ...
+Runs
+.B dpkg-buildpackage
+with some suitable options. Options and argumments after build
+will be passed on to dpkg-buildpackage. It is not necessary to use
+dgit build when using dgit; it is OK to use any approach which ensures
+that the generated source package corresponds to the relevant git
+commit.
+
+Tagging, signing and actually uploading should be left to dgit push.
+.TP
+\fBdgit build-source\fR ...
+Builds the source package, and a changes file for a prospective
+source-only upload, using
+.BR dpkg-source .
+The output is left in
+.IR package \fB_\fR version \fB.dsc\fR
and
-.B dgit fetch
-consult the archive and dgit-repos and fetch and/or construct the
-git view of the history. With clone, the destination directory (by
-default, the package name in the current directory) will be created,
-and the new directory's `origin' remote will be set up to point to
-the package's dgit-repos tree.
-
-.B dgit build
-runs
+.IR package \fB_\fR version \fB_source.changes\fR.
+
+Tagging, signing and actually uploading should be left to dgit push.
+.TP
+.B dgit clean
+Cleans the current working tree (according to the --clean= option in
+force).
+.TP
+.B dgit help
+Print a usage summary.
+.TP
+\fBdgit sbuild\fR ...
+Constructs the source package, uses
+.B sbuild
+to do a binary build, and uses mergechanges to merge the source and
+binary changes files. Options and argumments after sbuild will be
+passed on to sbuild. Changes files matching
+.IB package _ version _*.changes
+in the parent directory will be removed; the output is left in
+.IR package \fB_\fR version \fB_multi.changes\fR.
+
+Tagging, signing and actually uploading should be left to dgit push.
+.TP
+\fBdgit git-build\fR ...
+Runs
.B git-buildpackage
-with some suitable options. Options after
-.B build
-will be passed on to git-buildpackage. It is not necessary to
-use dgit build; it is OK to use any approach which ensures that
-the generated source package corresponds to the relevant git commit.
-Tagging and signing should be left to dgit push.
-
-.B dgit push
-does an `upload', pushing the current HEAD to the archive (as a source
-package) and to dgit-repos (as git commits). This also involves
-making a signed git tag, and signing the files to be uploaded to the
+with some suitable options. Options and argumments after git-build
+will be passed on to git-buildpackage.
+
+Tagging, signing and actually uploading should be left to dgit push.
+.TP
+\fBdgit push\fR [\fIsuite\fP]
+Does an `upload', pushing the current HEAD to the archive (as a source
+package) and to dgit-repos (as git commits). The package must already
+have been built ready for upload, with the .dsc and .changes
+left in the parent directory. It is normally best to do the build
+with dgit too (eg with dgit sbuild): some existing build tools pass
+unhelpful options to dpkg-source et al by default, which can result in
+the built source package not being identical to the git tree.
+
+In more detail: dgit push checks that the current HEAD corresponds to
+the .dsc. It then pushes the HEAD to the suite's dgit-repos branch,
+makes a signed git tag, edits the .dsc to contain the dgit metadata
+field, runs debsign to sign the upload (.dsc and .changes), pushes the
+signed tag, and finally uses dput to upload the .changes to the
archive.
-.SH MODEL AND WORKFLOW
-You may use any suitable git workflow with dgit, provided you
-satisfy dgit's requirements:
-dgit maintains a pseudo-remote called
-.BR dgit ,
-with one branch per suite. This remote cannot be used with
-plain git.
+dgit push always uses the package, suite and version specified in the
+debian/changelog and the .dsc, which must agree. If the command line
+specifies a suite then that must match too.
-The
-.B dgit-repos
-repository for each package contains one ref per suite named
-\fBrefs/dgit/\fR\fIsuite\fR. These should be pushed to only by
-dgit. They are fast forwarding. Each push on this branch
-corresponds to an upload (or attempted upload).
-
-However, it is perfectly fine to have other branches in dgit-repos;
-normally the dgit-repos repo for the package will be accessible via
-the remote name `origin'.
-
-dgit push can operate on any commit which is a descendant of the
-current dgit/suite tip in dgit-repos.
-
-Uploads made by dgit contain an additional field
-.B Vcs-Dgit-Master
-in the source package .dsc. (This is added by dgit push.)
-This specifies a commit (an ancestor of the dgit/suite
-branch) whose tree is identical to the unpacked source upload.
-
-Uploads not made by dgit are represented in git by commits which are
-synthesised by dgit. The tree of each such commit corresponds to the
-unpacked source; the single parent is the last known upload - that is,
-the contents of the dgit/suite branch.
-
-dgit expects repos that it works with to have a
-.B dgit
-remote. This refers to the well-known dgit-repos location
-(currently, the dgit-repos project on Alioth). dgit fetch updates
-the remote tracking branch for dgit/suite.
+If dgit push fails while uploading, it is fine to simply retry the
+dput on the .changes file at your leisure.
+.TP
+\fBdgit rpush\fR \fIbuild-host\fR\fB:\fR\fIbuild-dir\fR [\fIpush args...\fR]
+Pushes the contents of the specified directory on a remote machine.
+This is like running dgit push on build-host with build-dir as the
+current directory; however, signing operations are done on the
+invoking host. This allows you to do a push when the system which has
+the source code and the build outputs has no access to the key:
+
+1. Clone on build host (dgit clone)
+.br
+2. Edit code on build host (edit, git commit)
+.br
+3. Build package on build host (dgit build)
+.br
+4. Test package on build host or elsewhere (dpkg -i, test)
+.br
+5. Upload by invoking dgit rpush on host with your GPG key.
+
+However, the build-host must be able to ssh to the dgit repos. If
+this is not already the case, you must organise it separately, for
+example by the use of ssh agent forwarding.
+
+The remaining arguments are treated just as dgit push would handle
+them.
+
+build-host and build\-dir can be passed as separate
+arguments; this is assumed to be the case if the first argument
+contains no : (except perhaps one in [ ], to support IPv6 address
+literals).
+
+You will need similar enough versions of dgit on the build-host and
+the invocation host. The build-host needs gnupg installed, with your
+public key in its keyring (but not your private key, obviously).
+.TP
+.B dgit setup-mergechangelogs
+Configures a git merge helper for the file
+.B debian/changelog
+which uses
+.BR dpkg-mergechangelogs .
+You can use this in any git repository, not just ones used with
+the other dgit operations.
+.TP
+.B dgit quilt-fixup
+`3.0 (quilt)' format source packages need changes representing not
+only in-tree but also as patches in debian/patches. dgit quilt-fixup
+checks whether this has been done; if not, dgit will make appropriate
+patches in debian/patches and also commit the resulting changes to
+git.
+
+This is normally done automatically by dgit build and dgit push.
+
+dgit will try to turn each relevant commit in your git history into a
+new quilt patch. dgit cannot convert nontrivial merges, or certain
+other kinds of more exotic history. If dgit can't find a suitable
+linearisation of your history, by default it will fail, but you can
+ask it to generate a single squashed patch instead.
+.TP
+.B dgit version
+Prints version information and exits.
+.TP
+.BI "dgit clone-dgit-repos-server" " destdir"
+Tries to fetch a copy of the source code for the dgit-repos-server,
+as actually being used on the dgit git server, as a git tree.
.SH OPTIONS
.TP
-.BR --dry-run | -n
+.BR --dry-run " | " -n
Go through the motions, fetching all information needed, but do not
actually update the output(s). For push, dgit does
the required checks and leaves the new .dsc in a temporary file,
but does not sign, tag, push or upload.
.TP
+.BR --damp-run " | " -L
+Go through many more of the motions: do everything that doesn't
+involve either signing things, or making changes on the public
+servers.
+.TP
.BI -k keyid
Use
.I keyid
rather than looking in debian/control or debian/changelog.
Valid with dgit fetch and dgit pull, only.
.TP
-.BR -N | --new
+.BR --clean=git " | " -wg
+The source tree should be cleaned, before building a source package
+with one of the build options, using
+.BR "git clean -xdf" .
+This will delete all files which are not tracked by git. Also, -wg
+causes dgit to pass
+.B -nc
+to dpkg-buildpackage, which prevents the package's own clean target
+from being run.
+
+--clean=git is useful when the package's clean target is troublesome;
+the downside is simply that git clean may delete files you forgot to
+git add.
+.TP
+.BR --clean=none " | " -wn
+Do not clean the tree before building a source package. If there are
+files which are not in git, or if the build creates such files, a
+subsequent dgit push will fail.
+.TP
+.BR --clean=dpkg-source " | " -wd
+Use dpkg-buildpackage to do the clean, so that the source package
+is cleaned by dpkg-source running the package's clean target.
+This is the default. It requires the package's build dependencies.
+.TP
+.BR -N " | " --new
The package may be new in this suite. Without this, dgit will
refuse to push.
.TP
+.BR --ignore-dirty
+Do not complain if the working tree does not match your git HEAD.
+This can be useful with build, if you plan to commit later. (dgit
+push will still ensure that the .dsc you upload and the git tree
+you push are identical, so this option won't make broken pushes.)
+.TP
+.BI --deliberately- something
+Declare that you are deliberately doing
+.IR something .
+This can be used to override safety catches, including safety catches
+which relate to distro-specific policies. The meanings of
+.IR something s
+understood in the context of Debian are discussed below:
+.TP
+.BR --deliberately-not-fast-forward
+Declare that you are deliberately rewinding history. When pushing to
+Debian, use this when you are making a renewed upload of an entirely
+new source package whose previous version was not accepted for release
+from NEW because of problems with copyright or redistributibility.
+.TP
+.BR --deliberately-include-questionable-history
+Declare that you are deliberately including, in the git history of
+your current push, history which contains a previously-submitted
+version of this package which was not approved (or has not yet been
+approved) by the ftpmasters. When pushing to Debian, only use this
+option after verifying that: none of the rejected-from-NEW (or
+never-accepted) versions in the git history of your current push, were
+rejected by ftpmaster for copyright or redistributability reasons.
+.TP
+.BR --deliberately-fresh-repo
+Declare that you are deliberately rewinding history and want to
+throw away the existing repo. Not relevant when pushing to Debian,
+as the Debian server will do this automatically when necessary.
+.TP
+.BR --quilt=linear
+When fixing up source format `3.0 (quilt)' metadata, insist on
+generating a linear patch stack. If such a stack cannot be generated,
+fail.
+.TP
+.BR --quilt=auto
+When fixing up source format `3.0 (quilt)' metadata, prefer to
+generate a linear patch stack, but if that doesn't seem possible,
+generate a single squashed patch for all the changes made in git.
+This is not a good idea for an NMU in Debian.
+.TP
+.BR --quilt=smash
+When fixing up source format `3.0 (quilt)' metadata,
+generate a single squashed patch for all the changes made in git.
+This is not a good idea for an NMU in Debian.
+.TP
+.BR --quilt=nofix
+Check whether source format `3.0 (quilt)' metadata would need fixing
+up, but, if it does, fail. You must then fix the metadata yourself
+somehow before pushing. (NB that dpkg-source --commit will not work
+because the dgit git tree does not have a
+.B .pc
+directory.)
+.TP
+.BR --quilt=nocheck " | " --no-quilt-fixup
+Do not check whether up source format `3.0 (quilt)' metadata needs
+fixing up. If you use this option and the metadata did in fact need
+fixing up, dgit push will fail.
+.TP
.BI -D
Prints debugging information to stderr. Repeating the option produces
more output (currently, up to -DD is meaningfully different).
Specifies a git configuration option. dgit itself is also controlled
by git configuration options.
.TP
-.RI \fB--dget=\fR program |\fB--dput=\fR program |\fB--debsign=\fR program
-Specifies alternative programs to use instead of dget, dput
-or debsign.
+.RI \fB-v\fR version "|\fB_\fR | " \fB--since-version=\fR version |\fB_\fR
+Specifies the
+.BI -v version
+option to pass to dpkg-genchanges, during builds. Changes (from
+debian/changelog) since this version will be included in the built
+changes file, and hence in the upload. If this option is not
+specified, dgit will query the archive and use the latest version
+uploaded to the intended suite.
+
+Specifying
+.B _
+inhibits this, so that no -v option will be passed to dpkg-genchanges
+(and as a result, only the last stanza from debian/changelog will
+be used for the build and upload).
+.TP
+.RI \fB-m\fR maintaineraddress
+Passed to dpkg-genchanges (eventually).
+.TP
+.RI \fB--ch:\fR option
+Specifies a single additional option to pass, eventually, to
+dpkg-genchanges.
+.TP
+.RI \fB--curl=\fR program " | \fB--dput=\fR" program " |..."
+Specifies alternative programs to use instead of
+.BR curl ,
+.BR dput ,
+.BR debsign ,
+.BR dpkg-source ,
+.BR dpkg-buildpackage ,
+.BR dpkg-genchanges ,
+.BR sbuild ,
+.BR gpg ,
+.BR ssh ,
+.BR dgit ,
+or
+.BR mergechanges .
+
+For dpkg-buildpackage, dpkg-genchanges, mergechanges and sbuild,
+this applies only when the program is invoked directly by dgit.
+
+For dgit, specifies the command to run on the remote host when dgit
+rpush needs to invoke a remote copy of itself. (dgit also reinvokes
+itself as the EDITOR for dpkg-source --commit; this is done using
+argv[0], and is not affected by --dgit=).
+
+For ssh, the default value is taken from the
+.B DGIT_SSH
+or
+.B GIT_SSH
+environment variables, if set (see below). And, for ssh, when accessing the
+archive and dgit-repos, this command line setting is overridden by the
+git config variables
+.BI dgit-distro. distro .ssh
+and
+.B .dgit.default.ssh
+(which can in turn be overridden with -c). Also, when dgit is using
+git to access dgit-repos, only git's idea of what ssh to use (eg,
+.BR GIT_SSH )
+is relevant.
+.TP
+.RI \fB--curl:\fR option " | \fB--dput:\fR" option " |..."
+Specifies a single additional option to pass to
+.BR curl ,
+.BR dput ,
+.BR debsign ,
+.BR dpkg-source ,
+.BR dpkg-buildpackage ,
+.BR dpkg-genchanges ,
+.BR sbuild ,
+.BR ssh ,
+.BR dgit ,
+or
+.BR mergechanges .
+Can be repeated as necessary.
+
+For dpkg-buildpackage, dpkg-genchanges, mergechanges and sbuild,
+this applies only when the program is invoked directly by dgit.
+Usually, for passing options to dpkg-genchanges, you should use
+.BR --ch: \fIoption\fR.
+
+See notes above regarding ssh and dgit.
+
+NB that --gpg:option is not supported (because debsign does not
+have that facility). But see -k.
.TP
-.RI \fB--dget:\fR option |\fB--dput:\fR option |\fB--debsign:\fR option
-Specifies a single additional option to pass to dget, dput or
-debsign. Use repeatedly if multiple additional options are required.
+.BR -d "\fIdistro\fR | " --distro= \fIdistro\fR
+Specifies that the suite to be operated on is part of distro
+.IR distro .
+This overrides the default value found from the git config option
+.BR dgit-suite. \fIsuite\fR .distro .
+The only effect is that other configuration variables (used
+for accessing the archive and dgit-repos) used are
+.BR dgit-distro. \fIdistro\fR .* .
+
+If your suite is part of a distro that dgit already knows about, you
+can use this option to make dgit work even if your dgit doesn't know
+about the suite. For example, specifying
+.B -ddebian
+will work when the suite is an unknown suite in the Debian archive.
+
+To define a new distro it is necessary to define methods and URLs
+for fetching (and, for dgit push, altering) a variety of information both
+in the archive and in dgit-repos. How to do this is not yet
+documented, and currently the arrangements are unpleasant. See
+BUGS.
.TP
.BI -C changesfile
Specifies the .changes file which is to be uploaded. By default
dgit push looks for single .changes file in the parent directory whose
-filename suggests it is for the right package and version.
+filename suggests it is for the right package and version - or,
+if there is a _multi.changes file, dgit uses that.
+
+If the specified
+.I changesfile
+pathname contains slashes, the directory part is also used as
+the value for
+.BR --build-products-dir ;
+otherwise, the changes file is expected in that directory (by
+default, in
+.BR .. ).

+.BI --build-products-dir= directory
+Specifies where to find the built files to be uploaded.
+By default, dgit looks in the parent directory
+.BR .. ).
.TP
.BI --existing-package= package
-dgit push needs to canonicalise the suite name. But currently
-there is no way to ask the archive to do this without knowing the
+dgit push needs to canonicalise the suite name. Sometimes, dgit
+lacks a way to ask the archive to do this without knowing the
name of an existing package. Without --new we can just use the
package we are trying to push. But with --new that will not work, so
-we guess that
+we guess
.B dpkg
-exists in the target suite. If it doesn't, you can use this option to
-specify a package which does. If the suite is empty, bad luck.
+or use the value of this option. This option is not needed with the
+default mechanisms for accessing the archive.
+.TP
+.BR -h | --help
+Print a usage summary.
+.TP
+.BI --initiator-tempdir= directory
+dgit rpush uses a temporary directory on the invoking (signing) host.
+This option causes dgit to use
+.I directory
+instead. Furthermore, the specified directory will be emptied,
+removed and recreated before dgit starts, rather than removed
+after dgit finishes. The directory specified must be an absolute
+pathname.
+.TP
+.BI --no-rm-on-error
+Do not delete the destination directory if clone fails.
+.SH WORKFLOW - SIMPLE
+It is always possible with dgit to clone or fetch a package, make
+changes in git (using git-commit) on the suite branch
+.RB ( "git checkout dgit/" \fIsuite\fR)
+and then dgit push. You can use whatever gitish techniques you like
+to construct the commit to push; the only requirement is that it is a
+descendant of the state of the archive, as provided by dgit in the
+remote tracking branch
+.BR remotes/dgit/dgit/ \fIsuite\fR.
+
+If you are using dgit to do an NMU, and don't know about the
+maintainers' preferred packaging workflows, you should make your
+changes as a linear series of (logicially separated) commits on top of
+what's already in the archive.
+
+If you are lucky the other uploaders have also used dgit and
+integrated the other relevant git history; if not you can fetch it
+into your tree and cherry-pick etc. as you wish.
+.SH WORKFLOW - INTEGRATING BETWEEN DGIT AND OTHER GIT HISTORY
+If you are the maintainer of a package dealing with uploads made
+without dgit, you will probably want to merge the synthetic commits
+(made by dgit to represent the uploads) into your git history.
+Normally you can just merge the dgit branch into your own master, or
+indeed if you do your work on the dgit local suite branch
+.BI dgit/ suite
+you can just use dgit pull.
+
+However the first time dgit is used it will generate a new origin
+commit from the archive which won't be linked into the rest of your
+git history. You will need to merge this.
+
+If last upload was in fact made with git, you should usually proceed
+as follows: identify the commit which was actually used to build the
+package. (Hopefully you have a tag for this.) Check out the dgit
+branch
+.RB ( "git checkout dgit/" \fIsuite\fR)
+and merge that other commit
+.RB ( "git merge debian/" \fIversion\fR).
+Hopefully this merge will be trivial because the two trees should
+be the same. The resulting branch head can be merged into your
+working branches
+.RB ( "git checkout master && git merge dgit/" \fIsuite\fR).
+
+If last upload was not made with git, a different approach is required
+to start using dgit. First, do
+.B dgit fetch
+(or clone) to obtain a git history representation of what's in the
+archive and record it in the
+.BI remotes/dgit/dgit/ suite
+tracking branch. Then somehow, using your other git history
+plus appropriate diffs and cherry picks from the dgit remote tracking
+branch, construct a git commit whose tree corresponds to the tree to use for the
+next upload. If that commit-to-be-uploaded is not a descendant of the
+dig remote tracking branch, check it out and say
+.BR "git merge -s ours remotes/dgit/dgit/" \fIsuite\fR;
+that tells git that we are deliberately throwing away any differences
+between what's in the archive and what you intend to upload.
+Then run
+.BR "dgit push"
+to actually upload the result.

We should be using some kind of vhost/vpath setup for the git repos on
alioth, so that they can be moved later if and when this turns out to
be a good idea.
-Debian Policy needs to be updated to describe the new Vcs-Dgit-Master
-field (and to specify that it is an RC bug for that field to refer
-to an unavailable commit).
-
-The method of canonicalising suite names is bizarre. See the
-.B --existing-package
-option for one of the implication.s
-
dgit push should perhaps do `git push origin', or something similar,
by default.
+Debian does not have a working rmadison server, so to find out what
+version of a package is in the archive, or to canonicalise suite
+names, we ssh directly into the ftpmaster server and run psql there to
+access the database.

The mechanism for checking for and creating per-package repos on
alioth is a hideous bodge. One consequence is that dgit currently
only works for people with push access.
currently any mechanism for determining and honouring the archive's
ideas about access control. Currently only DDs can push.
-dgit's representation of format `3.0 (quilt)' source packages does not
-represent the patch stack. Currently the patch series representation
-cannot round trip through the archive. Ideally dgit would represent a
-quilty package with an origin commit of some kind followed by the
-patch stack as a series of commits followed by a pseudo-merge (to make
-the branch fast-forwarding). This would also mean a new `dgit
-rebase-prep' command or some such to turn such a fast-forwarding
-branch back into a rebasing patch stack, and a `force' option to dgit
-push (perhaps enabled automatically by a note left by rebase-prep)
-which will make the required pseudo-merge.

If the dgit push fails halfway through, it should be restartable and
idempotent. However this is not true for the git tag operation.
+Also, it would be good to check that the proposed signing key is
+available before starting work.
dgit's handling of .orig.tar.gz is not very sophisticated. Ideally
the .orig.tar.gz could be transported via the git repo as git tags.
Doing this is made more complicated by the possibility of a `3.0
(quilt)' package with multiple .orig tarballs.
-The error messages are often unhelpfully terse and tend to refer to
-line numbers in dgit.
+dgit's build functions, and dgit push, should not make any changes to
+your current HEAD. Sadly this is necessary for packages in the `3.0
+(quilt)' source format. This is ultimately due to what I consider
+design problems in quilt and dpkg-source.
+
+There should be an option which arranges for the `3.0 (quilt)'
+autocommit(s) to not appear on your HEAD, but instead only in the
+remote tracking suite branch.
The option parser requires values to be cuddled to the option name.
-dgit assumes knowledge of the archive layout. There appears to be no
-sane way to find the path in the archive pool of the .dsc for a
-particular suite. I'm assured that the archive layout is a
-`well known algorithm' by now.
+dgit assumes knowledge of the archive database. (The information dgit
+needs is not currently available via any public online service with a
+well-defined interface, let alone a secure one.)
---dry-run often does not work with fetch, even though this is a
-logically plausible request. (It fails, instead.)
+--dry-run does not always work properly, as not doing some of the git
+fetches may result in subsequent actions being different. Doing a
+non-dry-run dgit fetch first will help.
