This did not work.
However, changing it to the following DOES work:
/usr/share -maproot=0 defender.starwolf.com
/var/mail -maproot=0 defender.starwolf.com
/export/X11 -maproot=0 defender.starwolf.com
/export/local -maproot=0 defender.starwolf.com
However, if either /usr/share or /var/mail are different, multiple things
/var/mail lives on /var and is not a symlink elsewhere. Ditto /usr/share.
According to all premises of exported filesystems, something is still
And it should NOT be required in any particular order. That this is
so is just nuts. I don't know just what's going on.
For some reason, the mount_export() in mountd returns EPERM after the
mount_unexport(). This indicates to me that something is pointing to
the wrong place, either in the kernel or in mountd.c (and I cannot
yet determine which).
