Hi,

I didn't expect it either, honestly. In most cases, updates/installs
does go relatively painlessly if I don't mess up following
instructions/guides. In this case, I guess I just tripped up over the
unessential jrrd.

I've no idea honestly, my primary role isn't server admin and I'm just
winging it as I go along to support what I'm supposed to be doing with
the server.
The PG 8.4 was because we're developing something for our client who's
on that server, so I'm standardizing on 8.4 and likely will stick with
it for quite a while, rather than going with the 8.3 since there
appears to be quite a few changes in 8.4, especially on warm standby
features.
Apart from what's needed, I usually try to avoid installing things on
the public web servers we have.

Well, unfortunately, there's only that pair of machine in that
particular location. I really needed the monitoring tool up on it
because I've been noticing a higher than normal load since the
weekend. My quick hack of a PHP/cat /proc/loadavg script was also
alerting me consistently. After a couple of hours on opennms, it
became obvious that something was hitting the server. Turns out that
the client did not set the appropriate measures on their forum
software and bots were having a field day hitting it to break the
image recognition and finally got through to spamming.

Yup, it's pretty cool and that web interface really helps. While I am
perfectly at home using a text editor, I really don't want to have to
wade through and edit tons of text just to do something a few clicks
should handle.
Thanks again for pointing me to opennms :)
