ah ok -- i knew i would be able to mount other partitions but i was
curious about the boot partition -- i didn't know the VFS layer was
handling this (multiple mounts same FS) ... maybe i thought it was a
btrfs feature as i vaguely remember trying to mount an FS multiple
times in the past and getting an "already mounted" type of error.
this must have changed or i was doing something odd and didn't realize
it ... who knows :-)  thanks, i'll try it out.

nice ... i like these boot/recovery USBs but i tend to need/want
custom spins of certain <insert here> and i'm too lazy to spin my own
images every time i want to tweak something; i would find your
additions very useful.
