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

      Fix another corner case at the end of the image/slice being compressed. · c58b645e

      Fix up the print statements so that DOS slice numbering is consistent.
      Remove a few printfs that were not under the debug flag.

      This commit contains two signifcant changes: · 210aa1ec

      1. 'tb-set-hardware ... shark' and 'tb-set-hardware ... dnard' are now
      functionally identical.  Previously only the former worked but both passed
      the parser.
      
      2. Assign will now exit very quickly in the case that, for a given virtual
      nodes, there are no physical nodes that could match in type.  This should
      never happen as the parser and assign_wrapper have checks that usually
      prevent this.  However, in the case of problems in the code (such as #1)
      this'll make it easier to debug.  In addition, as we add more types of
      nodes and our estimates becoming increasingly inaccurate cases where this
      might occur could slip in.  All calling code treats this identically to an
      'insufficient resources' failure.

      Add new console_reset script to bulk reset all of the tip lines on · 4303838f

      plastic. Useful for when plastic reboots, although it needs to be
      run from paper of course. We should probably set up some kind of
      reboot utility for when plastic reboots, since when capture fires up,
      the "acl" files are all in the wrong group/mode. On the other hand,
      this shared file based permission scheme is going to end up changing
      anyway soon, since it won't work when the serial lines are on other
      machines. Will need a tip permserver at that point.

      Checkpoint new version of capture/tip that is sockets based instead · 34499cb6

      of pty/tty based (since they have several annoying problems
      associated). Note that permission is granted via the use of an "acl"
      file; /dev/tip/machine.acl, which must be set to the group of the
      project the node is in, so the user can read out the process id number
      and the random bits that are used by capture to grant permission to
      use (tip sends the random bits across first thing). This handshake is
      due to change to a request/challenge scheme as described by Dave in
      email to the testbed list.
