Good to see that autofa has been MFC'd during my vacation 8-)

But I found a little problem...

When I try to access the NFS exported file-systems on an older test 
machine (running 7.x, but that is not so relevant, it also happens with 
other servers), with the following exports:

$ showmount -e soekris
Exports list on soekris:
/var                               192.168.0.0
/usr                               192.168.0.0
/home                              192.168.0.0
/                                  192.168.0.0

I get:

$ ls /net/soekris
COPYRIGHT       dist            libexec         proc            tmp
bin             entropy         lost+found      rescue          usr
boot            etc             media           root            var
compat          home            mnt             sbin
dev             lib

which is correct, but the next level fails:

$ ls -l  /net/soekris/usr
total 0

since /usr on soekris is definitely not empty.
Relevant output of mount :

...
map -hosts on /net (autofs)
soekris:/ on /net/soekris (nfs, nosuid, automounted)

This is on 10.1-PRERELEASE r270922. The kernel config is GENERIC minus 
devices I do not have and AUTOFS added. Config files (/etc/auto_master, 
et al) are default. Mounting manually does succeed (in two steps, of 
course).

When trying this from Mac OS X (I am still on Snow Leopard) automounting 
works as expected. I did not have the opportunity yet to try a Linux box 
(also do not know whether autofs there has been eaten by systemd already 
8-)).

Do I miss something, or is this a bug?

Kind regards,

Hans
