Thanks for sharing your opinions. Answers inline.

I agree. I am not sure what hardware the schools have. I dont want to get a
"sync out of range" error everytime I run it. I dont want things to be
unsupported. I dont want to configure it manually after each install. I dont
want to compromise on the performance. After all, that's window's job ;-)

I'm thinking of using commercial compilers for compiling the things i need to,
like the kernel, the WMs etc., if they they are worth the speed. I have to
patch the kernel to include some of my own things also, so, cannot go for

I absolutely agree with you.

Linux BIOS? I'm talking distribution specific. But, it seems worth trying but
not worth the risk. After all, how much can a 13-yr-old do?

Correct. ReiserFS seems a better and faster choice. But, I really need the
undelete option not there in ReiserFS (Hans Rieser (IIRC, he is the creator
of reiserfs) says undelete is impossible in RieserFS). Is there any
journaling FS that supports undelete also?

Can you rephrase "resisting frequent resets" and "power outages the best"?

I was thinking of havng IceWM as first choice, XPDE as second, XFCE as third.
In one of the recent polls at some site about the best WM, they came out with
WMAKER as the winner. So, I'll add that too. Is it better to make it
selectable at the login time or through some utility that modifes the x
session files? I'm thinking of using a script that runs at login time to
select the WM. For login manager, I'm looking at GDM. It looks very cool and I
can add my school's logo there also. What say? Should I use GDM, KDM or
WINGSDM (IIRC, the Window maker DM)?

Yup, who cares?

A compile-it-yourself distro is more of a pain in the neck than a solution
when you have to install on multiple computers. LTSP is a better solution. I
can borrow somethings from K12LTSP and work it out.

Yes, LTSP is good choice.
I'm thinking of puitting gCompris, Dr.Geo, XaoS, things from debianJr, Wine,
things from freeduc and a lot of games also. What say? What else should I
Is BusyBox good enough for these kinds of distributions?
