[Beowulf] Gentoo in the HPC environment

[John Hearns]

Re. Putting bleeding edge packages on production systems I was once told to
put a new versiion of bash on an SGI Ultraviolet, running SLES.

Next time the system wouldn't boot.
Thank Seymour I had the systems admin skills to boot single user and force
a downgrade of the RPM.

The lesson- what SEEMS like an innocent change can have far reaching
consequences.
