crypted root, os-prober and grub-mkconfig

[Josef Wolf]

Hello,

with crypted root partitions (which should be pretty common on laptops
nowadays), os-prober is not able to find all installed linux flavors.
As a consequence, those flavors are no longer bootable after grub-install
(or grub-mkconfig).

Turns out that /usr/lib/os-probes/mounted/90linux-distro doesn't even try
to look for boot partitions. IMHO, it should be possible to parse grub.cnf
and menu.lst from the boot partitions to find all installed systems.

So what is the proper way to install multiple linux distros with crypted
roots on a laptop? Maybe there's a way to tell os-prober about additional
partitions to report?
