Why is has this changed?  Does it make it easier to do something on
the NetBSD side?  I don't see any gain here, only discomfort...
In particular, if you have a configuration like:

BSDR - root1
BSDS - swap
BSDH - root2
BSDE - /usr
BSDF - /home

You now won't be able to swap root1 with root2 (i.e. rename the
partitions under AmigaDOS to BSDH, BSDS, BSDR, ...)  to boot from an
alternate root without a) putting root2 at the end of your drive and
hacking /etc/fstab to flipflop amongst BSDE, BSDF, etc. and never
really know where the heck anything is, or b) making BSDE the name of
the second root partition.  Neither of these are very desirable
options for me...

Just my $0.02.  Maybe someone can enlighten me as to why this change
is a good one... 

Keep up the good work guys...
