647# - bulk patch handling similar to epatch()'s

649# - automatic patch uncompression like epatch()'s
650# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles

652# - once I decide it's production-ready, it'll be called from base_src_unpack

968# Usage: unpack_pdv [file to unpack] [size of off_t]
969# - you have to specify the off_t size ... i have no idea how to extract that

971# the size of the off_t type (in bytes) on the machine that built the pdv
972# archive. one way to determine this is by running the following commands:
973# strings <pdv archive> | grep lseek
974# strace -elseek <pdv archive>
975# basically look for the first lseek command (we do the strings/grep because
976# sometimes the function call is _llseek or something) and steal the 2nd
977# parameter. here is an example:
978# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
979# lseek
980# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
981# lseek(3, -4, SEEK_END) = 2981250
