Currently running NetBSD i386 1.6.1
I've downloaded the 2.0 sets to my /usr partition:
	/usr/downloads/NetBSD20/*

I had trouble the last time I upgraded (1.5.2 -> 1.6.1) using sysinst. 
Namely, I had trouble finding the downloaded sets on my disk from within 
sysinst (mounting the partition and getting the path right from within 
sysinst).  I was thinking of upgrading to 2.0 manually like we used to 
do in NetBSD-mac68k, by copying over the kernel, rebooting, then 
extracting all of the sets manually with tar or pax.

Will this work, or will there be problems?  The NetBSD INSTALL document 
says that upgrading using sysinst will replace the boot blocks. 
Obviously this will be skipped if I extract manually.
