Comment 76 for bug 807306

Davide,

The problem with removing /var/run and /var/lock and making them symlinks yourself is that this breaks all the various things that access sockets in either of these directories. If you do this on a desktop system, your desktop will be broken until reboot, and may not even shut down cleanly.

If you are going to make this change yourself, I recommend that you boot to single user mode, make the change, and immediately reboot. /var/run should point to /run; /var/lock should point to /run/lock.

I would still like to know why the automatic upgrade didn't work for you. If users are already running into problems with the migration at this early stage in the release cycle, I'm very concerned that this will break for many more users at the time of the beta - users who are going to be less able to help us diagnose the problem.
