Or NetBSD's way of interpreting disklabels or MBR.

Even if I install NetBSD on a USB stick, I would still put the source tree and 
pkgsrc on a hard-drive partition, likely the same partition I used for FreeBSD 
9.0-BETA1 .

I remember, under MBR and traditional BSD disklabels, how NetBSD overwrote the 
FreeBSD disklabel with its own on the FreeBSD partition.

First time, with FreeBSD 7.2 and no packages/ports installed, I could no longer 
access that partition until I installed FreeBSD 8.0.

Then with packages installed from ports, NetBSD again wrecked the FreeBSD 
disklabel, but this time, I had a backup copy and fixed the error, and FreeBSD 
was back in business as if nothing had gone wrong.  But I think now that bug 
has been fixed at the NetBSD end.

So I would be sure to keep a backup of the hard-drive partition table, GPT in 
this case, on a USB stick: a good idea, anyway.
