These are the steps the kludgey installer performs:

- Remove whatever rpm's conflict with athena rpm's (back then, it was
  sendmail) 

- From
  http://web.mit.edu/afs/athena/system/rhlinux/athena-<version>/free/RPMS
  get athena-{base,afs,rpmupdate} rpm's and install them.

- Start afs with "/etc/rc.d/init.d/afs start"

- cd to /afs/athena/system/rhlinux/

- Run 
  "/etc/athena/rpmupdate -h -p /dev/null control/list-<athena-version>"

- Copy /afs/athena/system/rhlinux/control/list-<version string> to
  /var/athena/release-rpms.

- Modify /etc/inittab, replacing each instance of "id:3" with "id:5"

- Put a line at the bottom of /etc/athena/version saying something like
  "Kludged install by SIPB on <date>
Athena Workstation (linux) Version <athena-version> <current-time>
"

It appears that for the 9.2 release, since it's currently in testing,
you need to change the paths to /afs/dev/ instead of /afs/athena.
