# image_install is used when installing a zone in a 'p2v' scenario.  In

# this case the zone install hook will branch off to this script which

# is responsible for setting up the physical system image in the zonepath

# and performing the various modifications necessary to enable a physical

# system image to run inside a zone.  This script sets up the image in the

# zonepath then calls the p2v script to modify the image to run in a zone.

# messages to the log file always, and verbose messages printed to the

# user if the user passes -v.  This rules out simple redirection.  And

# we can't use tee or other tricks because they cause us to lose the

# return value from the p2v script due to the way shell pipelines work.

#

# The simplest way to do this seems to be to hand off the management of

# the log file to the p2v script.  So we run p2v with -l to tell it where

# to find the log file and then reopen the log (O_APPEND) when p2v is done.
