If we can get a vgaue consensus on what it is that should be sourced,
I'd love to accept and integrate such a contribution... as long as
people who don't have something set still get their DB updated. Having
one set of packages everyone can use, and no one needing to build, is
high on the list of things the project has tried to do.
Perhaps it is possible to include a script in openafs with a mechanism
that allows the user to update his CellServDB. It should be called by
the init script. This mechanism could be triggered also by local update
methods (cfengine) or manualy.
What I would like to have is a something like this:
- A CellServDB.dist from openafs.org. Provided during installation and
perhaps updated by cronjobs via ftp or http.
- A CellServDB.local which I can maintain myself, perhaps with local,
nonpublic cells.
- A CellServDB.blacklist to exclude 'broken' cells (perhaps not up2date
in CellServDB.dist) or cells I don't want to be seen by my users on
all or some special clients.
These files can be processed by the update mechanism to form a new
CellServDB. If informations on new cells or modified cells are
distributed, the running client will be notified by the script (via fs
newcell, fs setcell).
We're using some tools based on a script from Dieter Mack (University of
Hohenheim) to maintain our CellServDB. A colleague (Rainer Laatsch) has
modified this for our environment and we have integrated it in our
cfengine setup.
This script, and some other tools to mangle the CellServDB, can be found
at /afs/rrz.uni-koeln.de/common/etc/.
The script newCellServDB reads the existing and a newly distributed
CellServDB, converts the entries in a list (per line: cellname and
serverlist) and compares the files. The client is notified if changes
occur.
newCellServDB+localadd merges a local file to a distributed CellServDB.
The rest works as in newCellServDB.
There are some other scripts in that directory, which might be useful too.

Berthold Cogel
