Hey Polytropon :-) I need large files over 4GB and some existing
access riight not to be modified so FAT does not apply, also extFAT is
patented so I wont give it even a try...

For archives maybe yes, but I need it as live r/w filesystem, just
like I used EXT2 - lets say three small OS partitions and one large
data partition on the workstation :-)

How about UFS2 driver for other OS? Is UFS2 endianness sensitive? Even
if, on one machine that would not be the problem :-)

Did anyone implement public UFS2 driver for other OS (Windows, Linux)?

Best regards :-)
