confirmed that the 'umount -lrf /isodevice' workaround works on the bionic iso of 2018/2/8. i didn't even use 'toram'.
everyone expects they need either burn a cd, use a thumb or external drive, or use another installer, eg mini.iso. with this workaround, or better yet if this bug gets fixed, none of those are necessary.
