Actually it looks as boring as hell.......

Yum?

Yet another *great* name picked for Linux crap programs.
Not as bad as Linpus, but close.

" yum-yum
colloq.
Nineteeth-century expressions for penis."

It figures.......

"Red Hat's response to update bind through RHN, patching the DNS hole, made
a fatal error which will revert all name servers to caching only servers.
The fix is easy enough, but this is a schoolboy error which I am surprised
Red Hat made. Unfortunately we were hit and our servers went down overnight
while RHN dropped its bomb and I am frankly surprised there has not been
more of an uproar about this."
