Maybe this is a dumb question, but why can't you mount the filesystem RW for
the session, make your changes, and then remount it RO?

I suppose you could do that, assuming you also configured to have a local shell on the client. You'd have to edit your NFS conf file to make the client chroot export read-write instead of read only and restart NFS. Then boot the client to a local shell and make your changes from there, and then change your settings back. That's why I suggested chrooting into the client root on the server. I thought it would be less work.

Here's a better question, why do you want to do this?

Because you can do it?

I didn't mean to sound smart, I was just trying to figure out what
you were trying to accomplish. The clients mount their minimal OS
read only. So if you want to make changes to the client chroot, you'd
have to chroot into the client root on the server (where you have
read-write access) to make your changes. I think you might need to
reboot the client to make some of the changes take effect (like if
you enabled SSHD on the client).


Maybe you want to check out exactly what kind of hardware unknown
thin client do have (lspci)? Or what it does right now (ps ax,
top)? Or what happens when you plug in USB stick (dmesg)?

With root enabled you can ssh in thin client and check out all
this. It is not the same thing as "chroot /etc/opt/i386".

Exactly, but you have to make the changes to the client root by
chrooting into it on the server.
That's all I was trying to say.
