# Description:
#  2003/04/11 the first version, only work on /dev/hda1 & PXE
#  2003/06/01 disk to disk mode & etherboot support 
#             (the etherboot lzdsk images are located in
#              /tftpboot/etherboot-5.0.7 after DRBLCD installed)

# Author: Steven Shiau <steven _at_ nchc org tw>
# 2003/07/21 the first version for Redhat, modified from Blake's version,
# only work on /dev/hda1 & PXE
# 2004/02/04 add the multicast function
# 2005/01/21 add code to save/restore some partitions (not entire disk).
# 2005/11/06 Many thanks to Christian Treczoks for providing "dd skip=1" method
# 2006/05/06 Remove save & restore hda1, since we can use save & restore partitions.
# 2006/12/07 Rewrite drbl-ocs to drbl-ocs + ocs-sr + ocs-functions.

# input parameters:
# save/savedisk/saveparts/restore/restoredisk/restoreparts/multicast_restore/multicast_restoredisk IMAGE-NAME DEVICES

# Notes:
# task_restorexxx/savexxx function will always use $ocsroot (/home/partimag) as mount point to do the save/restore, so it might overwrite the /home/partimag by mounting $ocsroot from server:/home2 (for example).
# The mount action is done in function task_preprocessing
