962# strings <pdv archive> | grep lseek
963# strace -elseek <pdv archive>
964# basically look for the first lseek command (we do the strings/grep because
965# sometimes the function call is _llseek or something) and steal the 2nd
966# parameter. here is an example:
967# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
968# lseek
969# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
