I don't think this will affect us, but in case anything in the release
depends on the naming conventions, here is a message describing the
naming convention that Operations has proposed and begun to put into
effect.

Long ago, there was general agreement within Operations Systems
Support on a standard I proposed for server cnames (aliases). Thanks
to Ron Hoffmann, we now have these cnames in effect for 47 servers.
(A few are names for machines that are not yet in service.) If we
consistently use these conventions when adding new machines, one day
all Athena servers will have short, algorithmic aliases.
First, the definitions:
------------
Fileservers (NFS, RVD or AFS): srvN-M <Room #>-M
Printservers: psrvN-M <Room #>-M
Hesiod Servers: hesM <Room #>-M
------------
"Room #" is the full MIT number for the room, including an 'm' (for
"main campus") preceding main-campus building numbers, which would
otherwise start with a digit. (eg: e40-342, m4-035)
'N' is the short form of the building number, actually used to refer
to the subnetwork on which the machine resides. The servers with
addresses beginning with "18.74", for example, are all on what we call
the building 4 network, though they may reside in different buildings,
and have cnames beginning with "srv4-" or "psrv4-".
'M' is an incrementor, used to distinguish between machines that share
all other components of the name.
Note that the second of each of the cname pairs above (the ones with
"Room #") are identical to the workstation name/cname convention used
by Network Services.
Some examples, from the list below:
Talos has the cname "m11-135-5" because it is in MIT room 11-135, and
was the 5th machine in 11-135 to be assigned such a alias. It also
has the cname "srv4-5" because it is a fileserver on the building 4
network, and was the 5th fileserver from building 4 network to be
assigned such a alias.
Blanket has the cname "m11-226-3" because it shares room 11-226 (the
IS Dispatch area) with at least two other computers. It also has the
cname "psrv11-1" because it is a printserver on the building 11
subnet.
There are, of course, exceptions. For example, apollo is missing its
location-alias (m11-135-<num>), m66-080-p is not in 66-080 (but the
printer is), etc.
What follows is a list of all the servers currently using the above
naming conventions.
