The Hurd and Linux variants of ext2 are compatible and can be
converted on the fly. You specify the "owner" (-o) so that the other
os will not add or delete things while accessing the disk. AFAIK
settrans will refuse to work on an ext2fs owned by linux.

But you can, for example, make a directory on a Hurd partition under
Linux, and later use settrans on that when under the Hurd. Same for
world-permissions, when we have fileutils that support them.
