Yes. But in the config above, you have 4+3=7 partitions. We can put extended
partitions in an extended partition, but I don't know if other OSes
can handle that.
This also mean that partitions informations are distributed among all the disk,
so you increase probability to loose parts of it.
I'd prefer to keep the possibility of a centralised partitions info, at last
for NetBSD-only disks.
The advantage of the actual system is that you have in NetBSD a partition
layout indepedant of the other OSs sharing the same disk.
The incovenient is that the user has to make a NetBSD partition table
coherent with the other OSes.
