It should work fine with ext3, reiserfs and xfs with kernel 2.6. With 2.4 only ext3 is functional (although it is somewhat faulty). I have patches for 2.4 if anyone wants, didn't try to push them through yet and I doubt they will be accepted as 2.4 doesn't take too many changes other then bug fixes anymore. > -- > TimC -- http://astronomy.swin.edu.au/staff/tconnors/ > A sysadmins description of life: > Even if the underpowered inter-continental links could take it, > you'd see a routing nightmare.
