nice, but what if you have blue AND green lights on your servers!

seriously, once at a large site (65 servers), we has
something similar, but it was very pedestrian, not
much more than a loop that did 'ssh $2@$groupnode
$3' for each computer in group $1. clusterit looks
much more developed... that was the same site where
the admin got all pissed at me because my rsync cron
deleted 4 hours of his dev work on a production
machine, after he had forgotten we agreed the
consultant, me, would set up the rsync cron.

really so many ways to do change management, but
if all the admins don't agree, none of them work.

nice to see the the glider hacker emblem, I forgot about that,
interesting mouse over too... didn't dig it out of all the css,
is it free?

I looked at the bash performance toolshed too, will have to post a
couple bash bugs I came across recently. (or maybe someone can tell me
why they aren't bugs!) a script breaks (doesn't reiterate the recursion)
when I take out the debugging echo "here I am" lines, and the printf
builtin fails to do the "\n" even " \n" when it should... I got to
reproduce the problem outside the script, maybe this weekend.
