It is probably just working out what you need to do - then using
the 'tool' versions of the programs to set the disk up.
IIRC you need (for i386/amd64):
1) type 169 mbr partition - probably the entire disk, with the mbr boot code.
2) bootxx_ffsv<x> copied to the start of the mbr partition
3) netbsd disklabel in sector 1 of the partition
5) untar the install sets
6) update the machine-specific config files
7) copy the required kernel to /netbsd
8) anything I've missed.
If you do (2) before (3) you can use dd instead of installboot.
sysinst really doesn't do anything clever, it is a lot of tests (etc)
to allow for all sorts of different disk partitioning choices.
