28# utility to pack and unpack a boot/root archive
29# both ufs and hsfs (iso9660) format archives are unpacked
30# only ufs archives are generated
31#
32# usage: pack   <archive> <root>
33#        unpack <archive> <root>
34#        packmedia   <solaris_image> <root>
35#        unpackmedia <solaris_image> <root>
36#
37#   Where <root> is the directory to unpack to and will be cleaned out
38#   if it exists.
39#
40#   In the case of (un)packmedia, the image is packed or unpacked to/from
41#   Solaris media and all the things that don't go into the ramdisk image
42#   are (un)cpio'd as well
43#
44# This utility is also used to pack parts (in essence the window system,
45# usr/dt and usr/openwin) of the non ramdisk SPARC
46# miniroot. (un)packmedia will recognize that they are being run a SPARC
47# miniroot and do the appropriate work.
