Comment 1 for bug 285013

Same here. Upgraded from 8.4 to 8.10, after which NFS shares aren't mounted anymore at boot (I don't remember any questions about conflicting configuration files while upgrading). The boot sequence hangs for a while when mounting the first shares. After several seconds it fails and the other NFS mounts fail immediately as well. Subsequent starting of NIS works OK, so by that time the network is up.
Switching to console after booting has finished and running mount -a as root mounts the shares correctly.

I'll give the aforementioned hack a try now.
