Because I missunderstood how that animal worked and simply removed the
uhelper option, claiming it did nothing - which is wrong. I was not
aware of that util-linux saved userspace only mount options in
/run/mount/utab. I had never heard of utab nor read about it in any
documentation. I saw the code passed over the uhelper=udisks option
but i never saw the option enter /proc/mounts and wrongly assumed it
had to do with hal compatibility or similar.

As I can see there are 2 options:
1. patch udisks to support non-util-linux mount, in some kind of
fallback fashion with reduced functionality (you will not be able to
run "umount" from command line on mounts that was mounted from GUI)
2. patch busybox (compile time option which defaults to off) with
support for userspace only mount options. Drawbacks with this you
already know. There is no way to simple implement this without adding
tons of code. (well, we could store the userspace options in a more
sane format)

I wonder what the BSDs do with this...
