Funnily, I stumbled into the exact same problem today in a different context...
That behavior is very indirectly documented through the paragraph:
> Further jail(), jail_set(), and jail_attach() call chroot(2) internally,
> so they can fail for all the same reasons. Please consult the chroot(2)
> manual page for details.
I agree that the jail_attach(2) manpage should mention the other "common"
reason for getting EPERM (another reason is for the attach to be rejected by
the MAC framework, and there are still potentially others).
