/var is filling up yet again on my server and I'm wondering what I have
to do, continue to grow /var or delete some of the many rpms that exist
in /var/cache/rcd/patch_data?

The server is OES SP2. I patch it by:

1. running rug pl | less to see what is not installed
2. run rug pi patch-patch# to see what the patch is going to break
3. finally run rug pin patch-patch#1 patch-patch#2 etc...
4. if kernel update is applied, run '/sbin/lilo -v'
5. if necessary 'shutdown -r now'

When I'm finished running rug, all of the patches in the channel have
an "i" next to them indicating that they are installed.
