upgrade to testing

[MaD dUCK <madduck@madduck.net>]

hey guys,
i would finally like to pull one of my systems up to testing, but i
still can't really afford losing it, so i am a little cautious. i
guess i would simply like to know if anyone of you had previous bad
experiences with the dist-upgrade. i am on a laptop, currently running
potato with a custom kernel 2.4.4 and pcmcia-cs build. should i just
do it? it isn't reversible, is it?

and the other thing: where can i find apt-sources for the main,
non-US, non-free, contrib testing binary *and* source packages???

thanks!

martin;              (greetings from the heart of the sun.)
