Re: Good practices with bectl

Summary: Using bectl for upgrades

RELEASE=Whatever
> bectl create ${RELEASE}
> bectl mount ${RELEASE}
BASEDIR=/tmp/be_mount.XXXX # Use mount point returned by bectl mount

[freebsd-update method]
> freebsd-update -b ${BASEDIR} -d ${BASEDIR}/var/db/freebsd-update \
upgrade -r ${RELEASE}
> freebsd-update -b ${BASEDIR} -d ${BASEDIR}/var/db/freebsd-update install
# Ignore admonitions to reboot, since we're using a boot environment
> freebsd-update -b ${BASEDIR} -d ${BASEDIR}/var/db/freebsd-update install
> bectl activate ${RELEASE}
#> bectl activate -t ${RELEASE} # Failsafe (if the machine is too far away
to simply walk over and
switch to the old BE):
> reboot

[upgrade from source method]
> make DESTDIR=${BASEDIR} installkernel
> etcupdate -p -D $BASEDIR
