Well, I did that, but no luck ...
Rebooting lands only on "BIOS data check successful" message at boot, not going forward as it always did.
In the meantime I copied the content of the /proc/partitions into the text file named "partitions" and placed it after chrooting directly into the already empty /proc directory.
That way, both mkinitrd and lilo seemed to be working properly, issuing typical messages.
But rebooting machine stopped at "BIOS data check successful" again ...
For using an encrypted root filesystem you need an separate /boot partition, which is not encrypted.
The BIOS boot loader is not capable directly to use an encrypted device as boot device. The "problem" is common also to Windows (7/8), which use an separate boot partition (aka system partition) with 100MB size, for be able to boot an encrypted disk C:.
I have a separated and unencrypted /dev/sda1 as boot partition!
My LVM/Luks combination on the older machine worked like a charm for several years, surviving lots of kernel upgrades including the 3.7.1 one.
The one difference is that it uses ext3 as a main filesystem.
My newer LVM/Luks machine uses ext4 and I have an upgrading problem with it.
