30# Install a boot environment using the current FreeBSD source tree.
31# Requires a fully built world & kernel.
32#
33# Non-base tools required: beadm, pkg
34#
35# In a sandbox for the new boot environment, this script also runs etcupdate
36# and pkg upgrade automatically in the sandbox.  Upon successful completion,
37# the system will be ready to boot into the new boot environment.  Upon
38# failure, the target boot environment will be destroyed.  In all cases, the
39# running system is left untouched.
40#
41## Usage:
42# beinstall [optional world/kernel flags e.g. KERNCONF]
43#
44## User modifiable variables - set these in the environment if desired.
45# If not empty, 'pkg upgrade' will be skipped.
46NO_PKG_UPGRADE="${NO_PKG_UPGRADE:-""}"
47# Config updater - 'etcupdate' and 'mergemaster' are supported.  Set to an
48# empty string to skip.
49CONFIG_UPDATER="${CONFIG_UPDATER:-"etcupdate"}"
50# Flags for etcupdate if used.
51ETCUPDATE_FLAGS="${ETCUPDATE_FLAGS:-"-F"}"
52# Flags for mergemaster if used.
