The package stateless-server should have been installed on the server. This contains a command-line tool stateless-snapshooter.
You can obtain a list of protosystems by typing
stateless-snapshooter --list
You should take a snapshot of the protosystem by typing
stateless-snapshooter --new --protosystem DemoSystem
The tool performs the following steps internally:
Makes a copy of the file tree, using LVM's snapshot technology if the files are mounted on an appropriate device and the correct kernel module is loaded, or uses rsync otherwise
Cleans up the copy of the file tree by removing various temporary files that ought not be present in a snapshot.
Updates /etc/sysconfig/readonly-root to make the root filesystem read-only.
Updates /etc/sysconfig/kudzu to stop kudzu from asking questions about the hardware it detects when booting a client.
Updates the LDAP database to create a record of the snapshot.
