Actually, with LTSP and without Jailbait, you can upgrade the kernel on
the I-opener without opening the thing up. I'm just using an older kernel
because it works fine for me, so I see no reason to upgrade.
Anyway, here is generally how. First, you configure things on the LTSP side
to allow a root login locally on the I-opener. The way I did this doesn't
ask for a password, so it can be a major security problem as someone could
wipeout data local to the client. There is probably a way around it. Also,
the way I did it makes the login available on all clients. It isn't a
problem for me, so I haven't fixed it.
Once you've got that done, add enough to the binaries available to LTSP
clients so you can mount drives, lilo, and make the new kernel available
on NFS. Also, you'll need to start with a kernel that supports ext2 or
whatever filesystem you're booting from. The kernel on my site and in the
image does.
Since I haven't spent much time on it, I don't have better directions or a
password on the clients.
Also, this setup can be handy to recover an ailing fat client or server
(other than the LTSP server, of course).

Great! Have fun!
