Robert, cmdline=ipv6.disable=1
In /boot/uEnv.txt seems to shave a good bit of boot time off at system up, on Wheezy 7.8 rootfs, systemd disabled, and . . . $ uname -r 4.1.12-bone-rt-r16 I built that kernel myself using your guide, and origin/am33x-rt-v4.1 -b tmp-rt, but using the stock .config. Just figured I'd let you know in case the subject every comes up.
