##
|
|
# Install a boot environment using the current FreeBSD source tree.
|
|
# Requires a fully built world & kernel.
|
|
#
|
|
# Non-base tools required: beadm, pkg
|
|
#
|
|
# In a sandbox for the new boot environment, this script also runs etcupdate
|
|
# and pkg upgrade automatically in the sandbox. Upon successful completion,
|
|
# the system will be ready to boot into the new boot environment. Upon
|
|
# failure, the target boot environment will be destroyed. In all cases, the
|
|
# running system is left untouched.
|
|
#
|
|
## Usage:
|
|
# beinstall [optional world/kernel flags e.g. KERNCONF]
|
|
#
|
|
## User modifiable variables - set these in the environment if desired.
|
|
# If not empty, 'pkg upgrade' will be skipped.
|
|
NO_PKG_UPGRADE="${NO_PKG_UPGRADE:-""}"

# Config updater - 'etcupdate' and 'mergemaster' are supported. Set to an
|
|
# empty string to skip.
