The root file system is mounted to /mnt/clone and the networking information is modified in

Then the SSH keys are regenerated in such a way that they are unique for the new virtual
server. The new root file system is then unmounted, set offline, and detached. In the final
section, the LINUX01 user ID is logged on via XAUTOLOG. Because the shared PROFILE
EXEC file detects that the user ID is in a disconnected mode, it carries out an IPL of Linux from
minidisk 100.
You may want to SSH into the newly cloned Linux server.
Note: If the clone script fails, you can check that:
The configuration contains all of the correct information in /etc/clone/.
No other users have links to the clone’s read-write disks.
