I don't think you need to use "-r". Also, you're forgetting one of
the best things about boot environments: you can upgrade them even
when not booted into them. That's faster than upgrading the running
BE. Here is the procedure I use:
RELEASE=Whatever
sudo bectl create ${RELEASE}
sudo bectl mount ${RELEASE}
BASEDIR=/tmp/be_mount.XXXX # Use mount point returned by bectl mount
sudo freebsd-update -b ${BASEDIR} -d ${BASEDIR}/var/db/freebsd-update
upgrade -r ${RELEASE}
sudo freebsd-update -b ${BASEDIR} -d ${BASEDIR}/var/db/freebsd-update install
# Ignore admonitions to reboot, since we're using a boot environment
sudo freebsd-update -b ${BASEDIR} -d ${BASEDIR}/var/db/freebsd-update install
sudo bectl activate ${RELEASE}
sudo reboot
This general procedure works just as well if you're upgrading from source, too.
sudo make DESTDIR=${BASEDIR} installworld
sudo mergemaster -m $PWD -D $BASEDIR -U
-Alan
