This can be fixed by combining it with that other idea you love,
using "/" as separator and "//" as an escaped "/":

/usr -> /../ext2///dev//sda1///

Now you know an ext2 filesystem from /dev/sda1 is mounted starting
(as normal) at the root. Gee, you could encode a whole mtab line.

You did want to get rid of mtab, didn't you? Here you go!
