Comment 3 for bug 146557

I just saw this problem when upgrading feisty to gutsy. My problem occurred because cfsd was not running at the time the postinst script ran, so it hung while trying to stat64("/var/cfs"). After starting cfsd (/etc/init.d/cfsd start), the upgrade proceeded normally and ran to completion.

The cfs installation scripts should check to make sure cfsd is running.
