If /usr was nfs mounted on a machine, then /usr needs to be mounted before
nfsd was loaded, and portmap/rpcgen lives in /usr and nfsd requires one of
those. Not to mention there are probably other services loaded before nfsd
which may require nfs moutned directories. In general, it is a good idea
to first setup vital parts of the system (like networking or mounting
directories) before offering other services (such as nfsd).
Possible ways to fix this includes:
- do nothing, let those who run these circular nfs-mount systems fix it
themselves. Perhaps recommend -o bg in the handbook or something.
- setup a flag, nfs_mount_delayed="YES|NO" in rc.conf
- do something in fstab which distingushes nfs mounts which can be delayed
* a new nfs_delayed fstype [this screams EVILE HACK!], or
* a new "delayable" option (how's that different from bg?)
* overload the Pass number in fstab, nobody fscks over nfs anyway.
Thoughts?
