>Environment:

FreeBSD 4.0-RELEASE as an NIS client, static NFS mounts out of
/etc/fstab, and  nis first in /etc/host.conf

>Description:

Portmap is not started until until the pass2 portion of rc.network is
executed. However, network_pass2 is run after we mount NFS
filesystems.

This is problematic in some environments if you have have nis as one
of the 1st entries in the host search order in /etc/host.conf.  The
problem is that the resolver cannot contact portmap to realize that
ypbind isn't available.  So the machines sits at 
	Mounting NFS file systems.
for quite some time.  Long enough for somebody to assume the machine
is wedged.

>How-To-Repeat:

Change /etc/host.conf so that nis is first in the search order, add an 
nfs mount to /etc/fstab, reboot.

>Fix:

Start portmap before attempting any NFS mounts.

I suppose a shorter timeout when portmap cannot be contacted would
also be a good fix.
