Okay, here's the scoop. In the Athena document Managing Your Athena Account
(the only document to allude to personal groups), I have revised the old
reference to the group "system:username", so that the section now reads:
Here are some of the possible group specifications you can make (e.g.,
as a user-or-group field in an fs command), including several special
system-owned groups:
--------------------------------------------------------------------
Group Purpose
--------------------------------------------------------------------
system:authuser Any user with valid Kerberos tickets in the same
cell (e.g., under athena.mit.edu).
system:anyuser Any user, including AFS users not at MIT.
--------------------------------------------------------------------
system:expunge The process which runs automatically on your
fileserver to remove old delete'd files
permanently. This group is given ld access to
your directories by default, so that the process
can look up the old delete'd files and remove them.
--------------------------------------------------------------------
system:groupname A system-owned (Moira) group, whose members can be
edited with listmaint or blanche. To create a
group, contact Athena Accounts (send e-mail to
accounts@mit.edu). To see if a mailing
list is also a group, look at the list
information by typing: blanche listname -i
--------------------------------------------------------------------
NOTE: If you have an account created before 1997, you may already have a
group that has the same name as your username (i.e., system:username).
Because of the naming confusion between this group and your username,
and because these groups were underutilized yet took up system resources,
these personal groups are no longer automatically created for new user
accounts.
I will put an equivalent message in upcoming release notes, whenever that
is...
In other words, the Moira gods may stop issuing system:username groups,
as far as Athena documentation is concerned.
