Hope you don't mind me chiming in here, this obviously is a very complicated
case, a lot of ins, a lot of outs and what-have-yous.
My point was simply enjoy the ride. I personally often have more fun setting
up a system than using it. Yes, I'm a little bit geeky, who do you ask?! It
is possible to break hardware with software but there are not a whole lot of
ways to do it, really. I overclocked a GPU and it died some time after,
though at the time of the giving of the ghost it was not overclocked so I
can't even be sure I was to blame. And then you can wreck your disk if you
use the really funky low level tools where the manual page says about certain
parameters (in ALL CAPS no less just to get the message through I guess)
**EXPERIMENTAL - DO NOT USE**.
Besides that it's mostly smooth sailing. And since you said you usually make
backups regularly I see you already have a great habit. Never heard of a guy
who regretted he didn't backup... Back it up or lose it, it's not a matter of
if but when. So you're pretty much set.
One forum for potentially quick interaction and conversation on Trisquel and
other free software issues is the #trisquel IRC channel on freenode. Might be
your cup of tea... or not.
Peace and love and cuddly bunnies and so have a lot of fun with your
computing in freedom! (And now i'll put the cork in it.)
