+= Node Images
+
+== Summary
+
+The imaging process is executed by the commands 'omf load' and 'omf save'
+
+These provision a full disk image onto a set of nodes, and should work for any ext2/3/4 filesystem.
+
+After saving an image from one node, and loading it onto another, it will appear to the user that a copy of the hard disk has been made. Specifically, this is a block based copy, not a file based one.
+
+The baseline image is a recommended starting point, as this provisioning tool does not currently work with standard .iso or similar files, instead using a custom compressed .ndz format.
+
+== Baseline Image
+The baseline image has two users, root and native. Remote logon as root is not enabled, and passwordless logon as native is enabled. By default, it will allow this only from private IP addresses.
+
+WARNING: For nodes that may be accessable externally, [mobile nodes, tunnels to an external subnet, etc] it is YOUR responsibility to set credentials to prevent remote login.
+
+This can be done via the passwd command, and / or editing the file /etc/ssh/sshd_config
