This also drops automatic selection of the rc local scripts
based on the local distro. Distributions now should specify the paths
of the rc-local and halt-local scripts on the configure command line.
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.
Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.
The bits that used to be MIT continue to be MIT.
The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.
rc-local.service acts as an ordering barrier even if its condition is
false, because conditions are evaluated when the service is about to be
started.
To avoid the ordering barrier in a legacy-free system, add a generator
to pull rc-local.service into the transaction only if the script is
executable.
If/when we rewrite SysV compatibility into a generator, this one can become
a part of it.
1) Just ship rc-local as-is; don't worry about the 'local' name.
2) Don't install rc-local and prefdm to /etc ; just enable them globally for the system in /lib.
