# usage: coraid-update {update file} {AoE target}
# coraid-update depends upon sysfs mounted on /sys
# The destination must be,
# 1) an AoE target ready for I/O, and
# 2) not too big to be an update target
#
# Later, when CORAID appliances mark update targets with special ATA
# device identify content or special target content, a prompt should
# be added after the check of the target's size if the identifying
# content is not detected.
#
# The update file must either,
# 1) be an SR tarc file that looks OK to the local tar, or
# 2) any file not ending in ".tarc".
# size of update LUN in /proc/partitions is 40000
max=70000
