custom installation and deselect *ALL* sets...

 The following is the list of distribution sets that will be used.
 
    Distribution set         Selected
    ------------------------ --------
 a: Kernel (GENERIC)             No
 b: Base                         No
 c: System (/etc)                No
 d: Compiler Tools               No
 e: Games                        No
 f: Online Manual Pages          No
 g: Miscellaneous                No
 h: Test programs                No
 i: Text Processing Tools        No
 j: X11 sets                    None
>x: Install selected sets

set partition sizes...

 Free space will be added to the partition marked with a '+'.
 
        MB         Cylinders   Sectors   Filesystem
        64               184    131376   /
        32                92     65688   swap
         0                 0         0   tmp (mfs)
         0                 0         0   /usr
       338               972    694008   /var
         0                 0         0   /home
    Add a user defined partition
    Change input units (sectors/cylinders/MB)
   >Accept partition sizes.  Free space 0 MB, 4 free partitions.  

Let it continue, and select progress bar... It'll finish quickly then it's time to hit CONTROL+Z when this shows up to drop to a shell.

 The extraction of the selected sets for NetBSD-5.0.2 is complete.  The system
 is now able to boot from the selected harddisk.  To complete the
 installation, sysinst will give you the opportunity to configure some
 essential things first.
 




                           +-----------------------+
                           |>Hit enter to continue |
                           +-----------------------+

manual intervention

I'm going to only extract the kernel, base & etc in this example... Although you can certainly extract more...

cd /targetroot
mt -f /dev/nrmt0 rewind
mt -f /dev/nrmt0 fsf 1
tar -xmf /dev/nrmt0
mt -f /dev/nrmt0 fsf 1
tar -xmf /dev/nrmt0
mt -f /dev/nrmt0 fsf 1
tar -xmf /dev/nrmt0

Now we need to make some device files....

cd /targetroot/dev
./MAKEDEV std
./MAKEDEV ra0
./MAKEDEV pty0

Now we are done, and can let the installer finish. Just type in:

cd /

then hit CONTROL+D
