So in a traditional configuration, the CellServDB file that's created as part of the package configuration will include the IP addresses of the VLDB servers and no DNS is required at boot. Increasingly, people are moving towards using what OpenAFS calls dynroot with AFSDB (or now DNS SRV) records, which doesn't contact any AFS cells at boot but instead locates them by DNS queries. However, in that case the DNS query is not done until someone attempts to access a file in AFS; there is no DNS service required to start the client, only once someone attempts to access files under /afs. So either way, I don't think the openafs-client init script should declare a dependency on DNS. To mention, the reason why I try to avoid having adding init dependencies is that eventually it should be possible to put all of /usr in AFS, so AFS should be able to start before nearly everything on the system. This currently isn't possible due to some configuration which is applied using a binary in /usr after the initial boot, but I'm (slowly) working with upstream to find a way to avoid having to do that through a separate binary. -- Russ Allbery ([email protected]) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
