897# strings <pdv archive> | grep lseek
898# strace -elseek <pdv archive>
899# basically look for the first lseek command (we do the strings/grep because
900# sometimes the function call is _llseek or something) and steal the 2nd
901# parameter. here is an example:
902# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
903# lseek
904# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
