Koji Cleanup

[John Florian]

What do you all do regarding cleanup of old koji tasks?  Do you just whack 'em with
"find -mtime +N -delete" or is there something more appropriate?  I have 120G of
livecd spins from my nightly builds and while I have lots of disk space I'm also
suspecting that Koji is unconstrained until I do impose my own constraints.  True?

Also, perhaps related, can somebody explain to me how the --scratch affects spin-livecd
jobs?
