How about using long options for all options, e.g.
 --all-root,
 --force-uid=,
 --force-gid=, (seems squashfs uses such naming).

since I'd like to leave short options for more common usages.

And you might need to update manpage as well, so I can apply it
ASAP...

(Btw, even compact inodes have 16-bit ranges, we could introduce
 some mapping table to remap sparse uid/gid into a compact form,
 if that is what you want, you could help to implement it as well :) )

Thanks,
Gao Xiang
