>Description:
from amd.conf:
[ /proj ]
map_name =              /etc/amd/proj

from /etc/amd/proj
/defaults       type:=nfs;sublink:="${key}";\
                opts:=rw,hard,grpid,intr,nodevs,nosuid
www             rhost:=shelly;\
                rfs:=${autodir}/${rhost}${path/}-2;fs:=${rfs}

from /etc/rc.conf
amd=YES
amd_flags="-r -l syslog -x error,noinfo,nostats"
amd_dir=/net                    # mount dir

from /etc/fstab
/dev/wd1f /net/shelly/proj-2    ffs     rw,nodev,nosuid                  7 2

Since /net/shelly/proj-2 is already mounted, amd -r is supposed to not try 
to mount the filesystem. When amd is started, it hangs when the filesystem
is referenced. This situation has been confirmed by Kimmo Suominen.

>How-To-Repeat:
See above.
>Fix:
I backed out the amutils binaries to the version supplied in 1.6 release, and
amd is mostly functional, though it froze up once in the past 2 months.
