Yes, but this option (CONFIG_UFS_FS_WRITE) is marked "EXPERIMENTAL" in
the kernel config, I believe, and the notes suggest it can be dangerous.

You could simply copy all the files and directories from a UFS
filesystem to an ext2/3 filesystem. Check out 'cp -a' for an easy
way.
(I should also mention the fun and educational double-tar method -- the
first thing that came to my mind, and what I'd probably do -- but I know
from personal experience that 'cp -a' is somewhat more, ahem, foolproof.
If only because there's only one invocation to get right. :)
