As with many of Life's other little quandrys, managing CellServDB
has an upside to balance the downside:
+ you have some "control" about which cells are accessible.
+ (correct me if I am wrong, but..) I think that because DNS
is _not_ involved in AFS, you have continuity in the event
of nameserver outage.
+ CellServDB is a useful reference of what cells are "out there"
+ Setting up "merged access" to internal (corporate-wide) and
external (Internet) sites is possible by merging appropriate
CellServDBs (plus cell mounts, default routing to the Internet,
and firewall config).
A simple answer is to automate CellServDB syncronization using cron.
One example of how to do this can be found in [1].
Cell mounts can be made current with "mk-afs-sync-mounts" [2]
Hope this helps!
