988# it seems to like to segfault a lot :(. So lets take it apart ourselves.
989#
990# Usage: unpack_pdv [file to unpack] [size of off_t]
991# - you have to specify the off_t size ... i have no idea how to extract that
992# information out of the binary executable myself. basically you pass in
993# the size of the off_t type (in bytes) on the machine that built the pdv
994# archive. one way to determine this is by running the following commands:
995# strings <pdv archive> | grep lseek
996# strace -elseek <pdv archive>
997# basically look for the first lseek command (we do the strings/grep because
998# sometimes the function call is _llseek or something) and steal the 2nd
999# parameter. here is an example:
1000# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1001# lseek
1002# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
