+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.
