Why doesn't Linux support ZFS?

If does! In user mode through FUSE. Just the same way as, I've heard,
if you're really determined you can implement NTFS under OpenSolaris.

I know ;-)

My question was meant rhetorically...

Anyway, both FUSE based solutions are really only a workaround. What I
wanted to imply with my question is: don't expect other systems than
Linux to support ext2/ext3, as Linux also doesn't support things like
ZFS out of the box.

One really has to live with the native filesystems an OS provides. Best
thing that you can get in common are SMB and NFS, as VFAT has almost no
features whatsoever and a lot of severe limitations (e.g. 4G file size
limit that hit me already a couple of times...)


There is no technical reason, only limited manpower, why OSol cannot
support ext2/ext3. On-disk format is stable and documented and here is
the solution:

SMB/NFS is good for migration if you have 2 systems but for small
business and dualboot it is not good enough.
How is small business relevant?

I simply can't seem to think of a reason why ext2/3/4 support is really useful for OpenSolaris; all the scenarios I can come up with can be equally served by using ISO or FAT or network sharing, or, frankly, the situation is contrived.


ext4 is different topic.

Best regards,

Milan
