Yep. I compiled both the alpha and beta releases of amd5.3 and had
exactly the same problem. amd was barfing on direct mounts.

* We had tried to compile amd because the IBM automounter at the time
did not support direct automounts.
* The current IBM automounter does allow direct automounts. But you
require these fixes:
IX26206 AUTOMOUNT COMMAND LINE SHOULD PROVIDE CAPABILITY TO POINT TO A
IX26196 NFS fails to mount due to sysuicp effecting biod
IX26195 AUTOMOUNT COMMAND LINE SHOULD PROVIDE CAPABILITY TO POINT TO A
IX26018 NEW AUTOMOUNT SYNTAX ERRORS -NULL MAP
IX25518 AUTOMOUNT EATS PAGING SPACE
IX25433 Required for Power Server 220
IX25275 /usr/lib/boot/tftp inslist entry should not list an oldpath
IX25228 the mkboot command does not allow /dev/network to be specified
IX25228 the mkboot command does not allow /dev/network to be specified
IX25202 Dump image corrupted because alignment is turned off.
IX24838 back out deltas for defect 45568
IX24837 backout code deltas for defect 42533
IX24807 Reconfig remote dump device delete the perm flag in arp table.
IX24802 message file changes for errpt -i and errclear -i options
IX24792 errpt and errclear need to accept alternate input filename
IX24034 USER CAN'T CHANGE MAXMBUF USING SMIT .
IX23857 AUTOMOUNT COMMAND LINE SHOULD PROVIDE CAPABILITY TO POINT TO A
IX22469 DBX COULD NOT WRITE INSTRUCTION MESSAGE.
IX22312 loader locking problem on remote shared libraries
IX21986 xsetrlimit(). EPERM not returned for neg numbers
IX21609 LOADER LOADS THE SAME LIBRARIES MORE THAN ONCE    

Most of these fixes are in 3.2.3 *except* for the big daddy IX26206. The
new manual page is not on the patch tape or 3.2.3. It has been posted
here before though.

We have not tried "amd" after installing these fixes because the IBM
automounter now *mostly* supports direct mounts. (It does not work if
the mount point is itself nfs mounted, which happens with our /usr
clients.) My guesses are:

* "amd" direct mounts will work correctly if you install the above
fixes. (I have them but until I have firm advice on the legalities of
making them available for ftp, I can't let you have 'em.)
* If it's only the "direct" capability that you want, then the IBM
automounter (after the above fixes) will be good enough. (Unless you
want to do something really *stupid* like automount /usr/local on a
/usr client. Why on earth would anyone want to do that?)
