It's generally not a good idea for system stability to move /var/run in
place to be honest. Lots of things use e.g. dbus for IPC and these will
likely just break badly.
Ultimately it's not the end of the world if you do the flip and do a
reboot, but all the same it's not ideal.
Also when changing them to symlinks it's important to ensure that
mandriva-clean-var-run-lock.service is disabled otherwise it will delete
the links again. I just did an "rm
/lib/systemd/system/sysinit.target.wants/mandriva-clean-var-run-lock.service"
in the conversion script.
