As announced by a few releases now, finally drop support for
sysvinit scripts.
Keep rc-local generator for now, as it's really a distinct
feature even though from the same era.
Instead, please use the kernel command line options with the same name.
I am not sure these files are System V complieant or not, but at least
they are very traditional way to control fsck or quotacheck.
However, the concept of the files are really broken, especially for
fsck. As when we want to fsck the root filesystem, we need to access the
filessystem, but it may be broken...
Let's drop such traditional ways to control fsck and quotacheck.
We already support kernel command line options to control the behaviors.
Maybe, also it is better to provide ways to control them by credentials.
That file contains a bunch of entries of which only some are related to SysV.
The rest are just "traditional APIs" that need to stay. In particular,
/var/lock a.k.a. /run/lock is used by many programs (LVM, iscsi, alsactl).
Similarly, the README about /var/log is something that should stay as long as
we have people migrating from older systems or using the copiuos documentation
that mentions /var/log/messages.txt on the Internet.
/var/lock/subsys is only used by sysvinit, and our code to support /forcefsck,
/fastboot, and /forcequotacheck is conditionalized on HAVE_SYSV_COMPAT, so
conditionalize those here on HAVE_SYSV_COMPAT too.
(This excludes any dirs that contain resources placed there by the user)
(I also didn't bother marking resources belonging to components that are
really not optional for us)
This moves the /var/log/README content out of /var and into the
docs location, replacing the previous file with a symlink
created through a tmpfiles.d entry.
