# Before we boot we validate and fix, if necessary, the required files within
# the zone.  These modifications can be lost if a patch is applied within the
# zone, so we validate and fix the zone every time it boots.
#

#
# BINARY REPLACEMENT
#
# This section of the boot script is responsible for replacing Solaris 10
# binaries within the booting zone with Nevada binaries.  This is a two-step
# process: First, the directory structure of the zone is validated to ensure
# that binary replacement will proceed safely.  Second, Solaris 10 binaries
# are replaced with Nevada binaries.
#
# Here's an example.  Suppose that you want to replace /usr/bin/zcat with the
# Nevada /usr/bin/zcat binary.  Then you should do the following:
#
#	1.  Go to the section below labeled "STEP ONE" and add the following
#	    two lines:
#
#		safe_dir /usr
#		safe_dir /usr/bin
#
#	    These lines ensure that both /usr and /usr/bin are directories
#	    within the booting zone that can be safely accessed by the global
#	    zone.
#	2.  Go to the section below labeled "STEP TWO" and add the following
#	    line:
#
#		replace_with_native /usr/bin/zcat 0555 root:bin
#
# Details about the binary replacement procedure can be found in the Solaris 10
# Containers Developer Guide.
#

#
# STEP ONE
#
# Validate that the zone filesystem looks like we expect it to.
