smartos_update_image.txt

# This document describes updating the SmartOS boot_archive and /usr volumes.
#
# The boot_archive effectively contains /. If you want to make changes to SMF
# or so forth, you need to update the boot_archive.
#
# If you want to add things to /usr, such as drivers, you will need to update
# usr.lgz. It is compressed, so note the lofiadm -U and -C calls below. Once
# you have updated usr.lgz you will need to copy it back to the mounted
# boot_arhive.
#
# This work must be done on a Solaris system.
