Can you explain a bit more ??

What's that (WNPP) ??

Lot's of nice surprises whith kernel 2.4 ;-)

Not completely, work with 2.2.15 but doesn't compil with 2.2.16 AND
gcc-2.95.2-12 (last night tests). The answer from Ariel Eizenberg from
the mosix team :
"MOSIX compiles flawlessly with gcc 2.7.2 and egcs 1.1.2 (gcc-2.91)."
Some other guy has the same pb (debian 2.2, gcc-2.95.2) and swapping to
2.7.2 solve it.

Doesn't know that either ... And what's that stuff on free software and
MOSIX ???

GPLed ... 
It seems to be "free" enough for me.

We did run a mosix cluster on 12 pII (debian slink/potato) last summer,
and it ran
pretty well.
I'm playing with a 2/3 nodes cluster from time to time at home. Until
that last release,
I didn't have much problems.
