Further investigation reveals that this problem is probably caused by
duplicate hosts in our netgroups.
Actually, we have a netgroup that contains hosts with both unqualified
and qualified domain names, as in:
MyNetgroup (myhost,-,-) (myhost.dom.ain,-,-)
Names are then looked up and qualified by mountd, and do_mount()
is called twice for each host. The second call fails, and leaves an
empty export list.
It is unclear to me how and where this should be dealt with. Maybe
mount(2)
could return with EEXIST instead of EPERM when an attempt is made to
enter a duplicate host in the export list, and mountd could act
correctly upon
such an error?
Thomas.
