I think Dan's approach is a good way to go. If you try to do it all on
the client (C), it will have to determine:
1. Are the mounts broken?
2. Is the host (A/B) up and running yet?
It will have to repeatedly check the status of the mounts and the host.
If you check too often, you're wasting resources. If you don't check
often enough, the mounts may remain broken for longer than necessary.
The host should inform the client that it has restarted and is ready to
resume file sharing, and the client can fix the mount ASAP.
Now, how to actually fix the mount... I'll have to plead ignorance on that
count.
