In fact, systemd-hostnamed will warn + if nss-myhostname is not installed. Packagers are encouraged to + add a dependency on nss-myhostname to the package that + includes systemd-hostnamed. + + Note that D-Bus can link against libsystemd-login.so, which + results in a cyclic build dependency. To accomodate for this + please build D-Bus without systemd first, then build systemd, + then rebuild D-Bus with systemd support. + +WARNINGS: + systemd will warn you during boot if /etc/mtab is not a + symlink to /proc/mounts. Please ensure that /etc/mtab is a + proper symlink. + + systemd will warn you during boot if /usr is on a different + file system than /. While in systemd itself very little will + break if /usr is on a separate partition many of its + dependencies very likely will break sooner or later in one + form or another. For example udev rules tend to refer to + binaries in /usr, binaries that link to libraries in /usr or + binaries that refer to data files in /usr. Since these + breakages are not always directly visible systemd will warn + about this, since this kind of file system setup is not really + supported anymore by the basic set of Linux OS components. + + For more information on this issue consult + http://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken + +ENGINEERING AND CONSULTING SERVICES: + ProFUSION offers professional + engineering and consulting services for systemd for embedded + and other use.
