Subject: apt hangs for 25 seconds before acting if logind isn't running

Package: apt
Version: 3.0.3
Severity: normal
X-Debbugs-Cc: g1pi@libero.it

Before invoking dpkg to perform the work, apt-get connects to DBUS in
order to make the seat-manager inhibit shutdowns.

If you don't have systemd-logind or elogind running (because e.g. you
were forced to install elogind as a dependency, but you disabled
it), this hangs for 25 seconds, until dbus reports timeout on
org.freedesktop.login1.

A quick and dirty workaround consists in putting 

    DPkg::Inhibit-Shutdown "false";

in a file in /etc/apt/apt.conf.d.  I could not find references to that
option in apt.conf(5), and had to search in the source code
(apt-pkg/deb/dpkgpm.cc) to discover it.  Therefore I kindly ask the
developers to document it, maybe together with Binary::apt::Pager [1].

Perhaps I am an old beard, but IMHO a package manager that depends on an
external daemon (and more generally on libsystemd) for something that
could be implemented with a lock file is a terrible idea.  Sooner or
later, someone will rewrite "ls" or "date" to call into dbus, and maybe
also contact remote servers, just to be sure...

Best regards,
	g.

[1] BTW I've been seeing "WARNING: apt does not have a stable CLI
interface. Use with caution in scripts" for years, because of course why
add "| less" (or "| grep something") when you have a helpful internal
pager stuck in your throat?
