When a node with the secure boot dongle is freed, it goes into PXEWAIT in the context of the secure MFS. Previously we remained in "secure mode" (i.e., did not terminate with a TPMSIGNOFF) while a node was in this state. If the next use of the node, just booted from the OS that was already on the disk, then we never signed off properly. Now we sign off before entering PXEWAIT. I thought that this would be the easiest alternative to fixing the problem..HaHaHa..not! Because now we have to restart the secure boot path (i.e., reboot) if the result of coming out of PXEWAIT is a request to reload the disk (i.e., if we are continuing the secure disk load path). Ideally this would have required only modifications to the state machines for SECUREBOOT/LOAD, but as you can see by the presence of stated.in in the modified files, this was not the case. The change required some additional "finesse" to get it working. See the comments in stated.in and bootinfo_mysql.c if you really care.
