I started reading this thread yesterday morning and was going to
reply, but it seems my motherboard started going south ... lockups
followed, ultimately, by no video.
Looks like I'll be testing my restoral scheme ... but, for now:
1) I'm using Knoppix on a 400MHz Celeron and it could use a bit of
memory. Anyone know where some PC133 ram can be obtained? PC
Warehouse (or whatever it is) over on MacArthur?
My "theoretical" recovery plan relies on regular rsynch's of /home
to /home2 (with an occasional manual tar to another machine). I find
myself wondering (like Darryl) how many of my bases I have covered. (Or,
perhaps thought of another way, what /etc type files will I encounter if
a new m/b is needed). I presume all the "precious stuff" is safe in one
or more of the three places /home, /home2 and/or tar files.
Drive config: (I'm assuming for now they're all ok)
hda: 20G or 30G WD w/Slack 10.
A cron regularly does an rsynch from /home to /home2.
1) The same motherboard could be thrown in and all would be good,
yes? (ie: if there are configurables in /etc, etc ...)
2) A different motherboard though, would require reinstalling the OS
on hda to get appropriate /etc type configurables.
But in both cases, /home and /home2 will mount up just fine with the
same OS ver (no lib conflicts, no problems ...)?
Presuming a different motherboard and, hey, might as well update
the OS, /home and /home2 will mount up, but some apps may have
This should be fairly easy, yes? (the nagging notion, what bases don't
I have covered?).
Am I missing anything obvious of a major nature?
ps: This discussion pretty much parallels Darryl's "easy user restore".
I'll still have to "restore" some stuff a typical user probably
wouldn't have (ie: Apache, some Perl modules, etc).
pss: Before the apparent complete death of the motherboard, I noticed
the "chipset" fan was apparently dying (spinning, then it would
slow down some, then spin up). Didn't notice any temp anomalies in
the krellm window. Could a bad fan result in crash, crash, eventually
no video even?
