[CentOS] URGENT: libdvdcss install hosed /var

I managed to get a partial solution running.  I rebooted from my
installation DVD and started to run an upgrade, but when it got to the
reboot part, I booted back to the DVD and ran 'linux rescue'.  I'm not
entirely sure what it did besides mangle my /etc/fstab (lost the nfs
/home mount), but I just happened to have a backup, so I remounted
/home and now everything seems to be working.

EXCEPT

The system is deathly slow in some areas.  OOo and Evolution take
forever to do the simplest things, although Seamonkey and the xterms
are working just fine.  I'm going to reboot again to see if that makes
any difference.

Bar.
