Hello,
I am not sure where to discuss these things, since I can't find the original
repository of os-prober.
While playing around with full-disk-encryption, I stumbled over two problems.
First problem is, that IMHO, the test for separate boot partition seems to be
inversed. Please check/comment this patch:
I think the original code is correct.
If the path is not found in the mounted ones it means: The boot-files
are direct on the main partition or the separat boot partition is yet
not being detected/mounted.

Second is a missing feature. OS on LUKS volumes wont be checked at all, even
if the partition is currently unlocked. Please check/comment on this patch:
