Yes, I would appreciate you having a look at this. I will need to build
a fresh rootfs to play with. This issue I am having is with a first-time
boot using the dhcp server; debootstrap --secondstage doesn't launch
because the system comes up with / mounted read-only. The console is
filled with a bunch of noise from the embedded processors, so I need to
dig to find the kernel boot messages.

John R. is adding more disk to linux-compile so I hope to have some room
to play in shortly.

Unless it's given you an error, it should be mounted r/w.  It won't
necessarily say it's mounted r/w when you use the mount command.  If it
isn't remounting it r/w then it could be an NFS permissions problem.
Check the exports file on the server.

Let me know if I can be of more help, like you want me to log into the
port and poke around or whatever.

Cheers,

a
