Linux distros changed /var/run and /var/lock to reside on an tmpfs in
/run a long time ago, and buildroot seems to agree by providing this
tmpfs on all supported init systems.
Packages on the other hand are currently free to either use /var/run
or /run, and similarly using /var/lock should be identical to the
replacement /run/lock.
This series aims to ensure that *if* /var/lock is needed, then
it will be a symlink to /run/lock. Allowing packages to continue
working and allowing them to migrate to using /run/lock.
If all relevant packages are fixed,
the compatibility symlinks in /var can be dropped.
Status before this patch:
* Systemd
/run will be mounted by PID1, /var/run will be recreated by
/usr/lib/tmpfiles.d/var.conf.
Creating /run/lock/subsys and the compatibility symlink is handled
in /usr/lib/tmpfiles.d/legacy.conf.
But this is *currently not installed* by Buildroot, see [1].
* OpenRC
Seems to check for existence of a /run directory and does all
necessary setup.
* SysV
/var/lock is currently a symlink to /tmp.
* Busybox
Same as sysv (Buildroot uses the sysv skeleton)
Note that we create /run/lock/subsys, so sysv scrips could expect this
directory to exist. Apart from simplifying scripts, creating the dir
early as root adds some security.
