Re: Problem building install kernel with ssh for NSLU2

[Donald T Hayford <don%donhayford.com@localhost>]

I was trying to avoid two difficulties.  The first was having to 
physically modify the NSLU2 to add in the serial port.  The second was 
needing a second NetBSD system that you can use to write the USB-Flash 
stick, since I was never able to figure out how to write to the disk 
with a system other than NetBSD.  If I had root on the flash disk, then 
it is a relatively simple matter to compile the kernel so that it boots 
up using the flash disk as root by changing a couple of lines in the 
config file for NSLU2.  Here's a diff for that:

--- NSLU2.orig    2008-02-13 22:28:59.000000000 -0500
+++ NSLU2    2008-02-13 22:28:19.000000000 -0500

+config        netbsd        root on sd0a type ffs

# The main bus device
mainbus0    at root

As long as the flash disk was setup to start sshd properly, then one 
could telnet into RedBoot to load the kernel and get it going, then 
switch to ssh to login to the NSLU2.  But as I said, I could never write 
the flash drive on another (Linux) system and get the NSLU2 to boot into 
it.  If you could point me in the right direction for that, I would 
greatly appreciate it.

Hmm, though reading this over I wonder if

config   netbsd   root on 192.168.1.102:/client/root type nfs

might work as well.  I know how to set up the NFS root.

Thanks, Don
