wanted: truly hairy amd map files
J Eric Townsend
I've been using amd for a few months now, but haven't dared trying
anything too cool. I just use simple direct mounts and drive on.
Now, I'm looking for some examples of really tricky things done with
amd.
I know that handing out this sort of information might compromise
one's system. All I can say is I promise not to use the information
for any other purpose than to learn amd map file tricks. flames, etc,
to /dev/null.

How about a "canonical" depot map?
It works together with the enclosed patches, written by Rodney
Peck, of RPI, and me.
It lets you do hierarchical mounts based on architecture. The maps
practically never require maintenance, and allow any host to
interchangeably perform the role of server and client, in a cooperative
way with other hosts.
Limitation: you cannot point the symbolic link filesystem, as I have
patched it, to another automount map.

X# This makefile is included by the yellow pages Makefile in order to
X# distribute these system automount tables in yellow pages data bases.
X# The yp makefile needs to have an 'include' of this file and the
X# target 'autotabs' added to its target 'all' in order for this to
X# work. klm 6-Jan-1990
X
X# In order to add a table as a yp map:
X#
X# - add it as a dependency of the 'all' target;
X# - add a target for it just like the others in the "Specific targets" section.
X#
X# The generic recipe below will then be invoked to do the right thing.
X#
X# Please be sure that a suitable map doesn't already exist before
X# instituting a new one. Also note that entirely new YP will not
X# successfully push to slave servers - you have to login to the slave
X# and do a /usr/etc/yp/ypxfr -h <master host> <new map name> in order
X# to institute the new map.
