    An attempt at making image creation an easy/automatic operation. HA! · 27f26d99

    This uses the pxe booted freebsd kernel and MFS. In addition, I use
    the standard testbed mechanism of specifying a startup command to
    run, which will do the imagezip to NFS mounted /proj/<pid>/.... The
    controlling script on paper sets up the database, reboots the node,
    and then waits for the startstatus to change. Then it resets the DB
    and reboots the node so that it returns back to its normal OS. The
    format of operation is:
    	create_image <node> <imageid> <filename>
    Node must be under the user's control of course. The filename must
    reside in the node's project (/proj/<pid>/whatever) since thats the
    directory that is mounted by the testbed config software when the
    machine boots. The imageid already exists in the DB, and is used to
    determine what part of the disk to zip up (say, using the slice option
    to the zipper). Since this operation is rather time consuming, it does
    the usual trick of going to background and sending email status later.
