Don't know anything about using NBD. How do I check?

But I have not changed any setting regarding chroot....whatever is default
is being done....don't know enough to do any customization ;-)

And it should BE SL? hmm...script buggy? or did I screw up? I assumed SL/EL
was default option and did not give any --release option.....Do I need to
give something like --release SL or EL or something similar?

I don't have my test system up to compare at the moment.

RAM in this particular machine is 128 mb.

We have machines from 128 mb to 256 mb lying junk with us, which we are
looking to use, in addition, we wish to add low power thin-clients.

And do you know what mode NIC they have?

NIC is Realtek RTL8029AS - a 10 mbps bnc/rj45 half-height card.

lspci confirms this.


On standard SL/EL install with rdshell command in kernel
parameters....error is again (I am assuming that SL/EL is booting and not
FC11 as being speculated above):

No root device found.
Dropping to debug shell.
sh: can't access tty: job control turned off
