	So this is weird, but I noticed that we have a mount binary in /usr/bin that seems to be earlier in our path than busy box's /bin/mount. So I just went and replaced all "mount" invocations in /lib/upgrade/common.sh with "busy box mount" and that seems to have done the trick (it upgraded and rebooted into a pristine 3.10.18-1, I am not sure whether the firmware partition was really overwritten, but the overlay partition surely was wiped). It seems that the option handling of /usr/bin/mount chokes on the actual mount invocations in that script (I noticed that the move of /proc failed and from then on it was downhill). I am not sure whether my modification to common.sh is not too ugly to live, but I assume that the grown-ups ail find a proper way to fix this now :) And what I currently do not understand is why the GUI method worked since that is just calling the sys upgrade script from "/"...

So I had a quick go at this one:

this should hide all confusing fields until htb_private or tc_stab are selected under the field named:
Which linklayer adaptation mechanism to use; especially useful for ADSL/ATM links.

So "none" will hide all the cruft. Since most of the options also can work with ethernet links (think PPPoE on a non-ATM carrier will still cause an 8 byte per packet overhead).
