Subject: bug#21843: Generated grub.cfg does not support encrypted roots
Date: Tue, 8 Mar 2016 20:33:09 +0100 [thread overview]
Message-ID: <20160308193309.GA2251@solar> (raw)
In-Reply-To: <20160308192104.GA22722@solar>
What is needed are the following two lines at the beginning of grub.cfg:
insmod luks
cryptomount -u 1aa...
where 1aa... is the result of "cryptsetup luksUUID /dev/sda2".
So the logic outlined in my previous message works:
Determine the mapped-devices /dev/sdXY of type luks-device-mapping that
lead to a file-system with needed-for-boot? set to #t.
Using
cryptsetup luksUUID /dev/sdXY
determine a corresponding uuid 12345...0.
If any such mapped-device exists, add
insmod luks
as the first line of grub.cfg. For any such mapped-device, add a line
cryptomount -u 12345...0
right after that.
To simplify the logic, we could also move the needed-for-boot? parameter
to mapped-device, or add such a parameter there.
Andreas
