Make filesystem read-write.

Hello,

Thanks to Oliver's suggestion, I can now login from the thin client 
using a tty. I've played around with it and it turns out that the client 
is mounting the file system as read-only:
$ cat > hello
-bash: hello: Read-only file system.


This would explain why I can't login from the GUI. When you login, X and 
Gnome will write a bunch of files to your home. And if it can't, you get 
kicked out. I've seen this before.
I've played around with /opt/ltsp/i386/etc/fstab on the server. But it 
looks like when the client boots, it is not reading this fstab file.
Can anyone think of a reason why the client would be mounting / as 
read-only? And how to make it not do that?
Thanks for the help.

Cheers,
Daniel.
