it happened to me just shortly after 10 was released, that I tried to
read a GELI partition with 9.0 which is supposed to work according to
the manual but did not work for me. After installing 10 on the affected
machine, everything worked. After seeing some notes on the page of my
favorit search engine that this is known, I did not bother to do
anything else.

Should I check when I have time if this is still the case with 10.1?
