29# utility to pack and unpack a boot/root archive
30# both ufs and hsfs (iso9660) format archives are unpacked
31# only ufs archives are generated
32#
33# usage: pack   <archive> <root>
34#        unpack <archive> <root>
35#        packmedia   <solaris_image> <root>
36#        unpackmedia <solaris_image> <root>
37#
38#   Where <root> is the directory to unpack to and will be cleaned out
39#   if it exists.
40#
41#   In the case of (un)packmedia, the image is packed or unpacked to/from
42#   Solaris media and all the things that don't go into the ramdisk image
43#   are (un)cpio'd as well
44#
