Really, there's no problem there.  If it's really ext2, it's trivial to add
a journal and turn it into ext3.  I wouldn't be surprised though if they
really mean ext2 with journalling:  ext3 is not a separate filesystem, it's
just ext2 with journalling.   "tune2fs -j ..."  Note, you'll want to use
tune2fs with the -C option, anyway, to reduce the frequency of fsck's,
which are much less necessary with ext3 than in ext2, though the defaults
are set the same.

No.  (Well, somebody does, but I'm happy with JFS).
