I have found a way to reconfigure the system to resolve the problem.
However, there is still a bug in the default configuration of Ubuntu.
The problem DOES appear to be name resolution.
Even with bind9 installed, the local system is never configured to set
/etc/resolv.conf to USE the local nameserver!
When I configured that manually, by editing /etc/resolv.conf, then rebooted, it
properly exported the filesystems -- for
a single boot. But then NetworkManager overwrote /etc/resolv.conf with its own
crazy idea of how to resolve domain
names, and on the second reboot, it failed to export the filesystems.
But this at least showed what the problem was. And enough talented
sysadmins had already seen THIS problem that they came up with a big
kludge script (apt-get install resolvconf) and patched all of the
applications that love to clobber /etc/resolv.conf to call it. So after
I installed the resolvconf package, and made sure that
/etc/default/bind9 was set to "RESOLVCONF=yes" so that it would
automatically inject localhost into resolvconf, everything started
working.
This problem CLEARLY should be fixed in the default configuration.
Forcing resolvconf and bind9 won't work, because the system can't know
how to configure bind9 so it'll locally store a cache of the domain
names that /etc/exports needs to resolve. I don't know how to fix this
-- the complexities of upchuck are beyond me. I think you'll have to
actually let upchuck know that, yes, /etc/exports MIGHT INDEED contain
domain names and MIGHT INDEED have to look them up, so if domain service
isn't yet working, then oops, DON'T RUN exportfs yet. Or, as an old
programmer warrior often told me, "I can make your program run
arbitrarily fast if you don't mind it producing the wrong answer."
Upchuck has to produce the right answer -- THEN make things as fast as
possible within that constraint.
