I've tried adding "mount" and "umount" to `setuid-programs' in my
operating-system config:

--8<---------------cut here---------------start------------->8---
(setuid-programs (cons*                                       
                  #~(string-append #$util-linux "/bin/mount") 
                  #~(string-append #$util-linux "/bin/umount")
--8<---------------cut here---------------end--------------->8---

Mounting as an unprivileged user now works as expected (even the fancy
9p stuff).  Is there any rationale for not adding "mount" and "umount"
to `%setuid-programs' by default?
