Would it be a no-no to use 'data' for > a non-fs-specific arg? I guess it would be OK for bind, but not for new- and remounts, where 'data' is already used. Maybe it's best to stay with fsuid after all, and live with having to restore capabilities. It's not so bad after all, this seems to do the trick: cap_t cap = cap_get_proc(); setfsuid(uid); cap_set_proc(cap); Unfortunately these functions are not in libc, but in a separate "libcap" library. Ugh.
