OK, that's a bit better, but I suppose I'd really like it to be
running something other than ext2 if possible. Was nothing else
supported in the Xebian kernel? That would be unfortunate. If ext3 is
supported then you could give it a journal now, right? (Need to check
that but I think you can turn the journal on and off when you want.)

Thanks for the info. This is all great learning.

Cheers,
Mark
