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