On my "main" NetBSD/pmax machine, I've never had /usr on local disk -
it's always been NFS mounted.  I've always just mounted the filesystem
on /usr.  Because you're using the /remotedrive thing, you'll probably
need to add /remotedrive to the "critical_filesystems" variable in
rc.conf.  What would be happening now is that /remotedrive won't be
mounted until well down in /etc/rc, and /etc/rc assumes /usr is mounted
earlier than this.

Anyways, here's (part of) my fstab:

	vlad:~ 1> head -6 /etc/fstab
	/dev/rz0a                       /               ffs     rw 1 1
	/dev/rz0b                       none            swap    sw
	kernfs                          /kern           kernfs  rw
	procfs                          /proc           procfs  rw
	balrog:/dlboot0/netbsd.pmax/usr /usr            nfs     rw
	balrog:/dlboot0/vlad.root/var   /var            nfs     rw

and the corresponding df:

	vlad:~ 2> df | head -6
	Filesystem                      1K-blocks     Used    Avail Capacity  Mounted on
	/dev/rz0a                           31453    22731     7149    76%    /
	balrog:/dlboot0/netbsd.pmax/usr   1770606  1127683   554393    67%    /usr
	balrog:/dlboot0/vlad.root/var     1770606  1127683   554393    67%    /var
	kernfs                                  1        1        0   100%    /kern
	procfs                                  4        4        0   100%    /proc

I'd recommend direct-mounting /usr without the symlink...
