118# Before we boot we validate and fix, if necessary, the required files within

124# BINARY REPLACEMENT
125#
126# This section of the boot script is responsible for replacing Solaris 10
127# binaries within the booting zone with Nevada binaries.  This is a two-step
128# process: First, the directory structure of the zone is validated to ensure
129# that binary replacement will proceed safely.  Second, Solaris 10 binaries
130# are replaced with Nevada binaries.
131#
132# Here's an example.  Suppose that you want to replace /usr/bin/zcat with the
133# Nevada /usr/bin/zcat binary.  Then you should do the following:
134#
135#	1.  Go to the section below labeled "STEP ONE" and add the following
136#	    two lines:
137#
138#		safe_dir /usr
139#		safe_dir /usr/bin
140#
141#	    These lines ensure that both /usr and /usr/bin are directories
142#	    within the booting zone that can be safely accessed by the global
143#	    zone.
144#	2.  Go to the section below labeled "STEP TWO" and add the following
145#	    line:
146#
147#		replace_with_native /usr/bin/zcat 0555 root:bin
148#
149# Details about the binary replacement procedure can be found in the Solaris 10
150# Containers Developer Guide.
151#
152
153#
154# STEP ONE
155#
156# Validate that the zone filesystem looks like we expect it to.
