Dear Mark, Thank you for this hint. ext2 is working but my clone is still not. I am still investigating why. It doe not find an /root/proc in /etc/fstab or /etc/mtab.
I was searching on the Internet regarding the best way of doing r/o root file system. And found following: http://en.opensuse.org/How-To_Make_the_root_filesystem_read-only and http://linuxvm.org/present/SHARE111/S9216rt.pdf What I don't really have is a blueprint for SLES 11. Unfortunately there is always a lot of change in the boot process and, at least to my knowledge, no clear documentation. I like the SHARE presentation very much. In principle I am looking for a simple way to ensure nobody can change the root and /usr and /opt directories. Currently under SLES 10 I have /etc, /tmp /var and /home on separate minidisks. What I would need is a how to to explain what is really needed from /etc during the boot process, especially in r/w mode. Isn't this similar to the process when I would put all that stuff into a z/VM DCSS?
