what's the difference if one runs the ffs async,noatime? atleast i noticed
that even on eide it makes it faster and causes less noise...

hehe... how hard something like that is to implement? i assume it's hard,
is it truly usefull?

what's the lfs status on freebsd?

cool... now we just need someone who ports freebsd to run on sgi hardware,
that'd be nice thing to have... the r10000 cpus have potential and the
architechture generally seems rather efficient. busses are wide and stuff...
