Thankyou to those who replied.
Task now completed.

For anyone interested in placing the pkg tree on a separarate partition be
warned. The expanded pkgsrc consists of LOTS of very small files. On a
standard newfs of a 130MB partition I ran out of inodes at 65MB. Doubling
them seemed to fix the problem.
For UNIX novices like me, halving the bytes per inode (default 4096) eg.
			newfs -i 2048 <volume>	(in my case sd0g)

I find the man pages are only now starting to become helpful due to the
high level of assumed knowlege in them (I have been following and playing
with NetBSD since 1.3)

Cheers
Richard
