Do not use the dbus-1.pc pkgconfig settings to determine dbus directories. Use
directories relative to ${sysconfdir} and ${datadir} instead.
This approach was suggested by Simon McVittie in:
http://lists.freedesktop.org/archives/systemd-devel/2014-October/024388.html
Tested by building and installing systemd without the dbus-devel installed.
Without this patch, the dbus files and directories end up in the root of the
filesystem. With this patch, they end up in the same locations as previously
(assuming default ${sysconfdir} and ${datadir}) whether dbus-devel is present
or not. Also made sure that `make check` works without dbus-devel installed.
I figure "pull-dck" is not a good name, given that one could certainly
read the verb in a way that might be funny for 16year-olds. ;-)
Also, don't hardcode the index URL to use, make it runtime and configure
time configurable instead.
It helps editing units by either creating a drop-in file, like
/etc/systemd/system/my.service.d/override.conf, or by copying the
original unit from /usr/lib/systemd/ to /etc/systemd/ if the --full
option is specified.
It invokes an editor on temporary files related to the unit files and
if the editor exited successfully, then it renames the temporary files
to their original names (e.g. my.service or override.conf) and
daemon-reload is invoked.
If the temporary file is empty the modification is canceled.
