Trying to make Mint GRUB2 boot OpenSUSE encrypted boot Help

Darkyere · 01-24-2017, 01:09 PM

I have succesfully made a fully encrypted system (Boot included) with linux mint now im trying to do the same with OpenSUSE and using Mint GRUB2 to load it.

But i simply cant make it works.

If anyone can assist at configuring Grub.cfg to unlock and encrypted boot i would highly appreciate it.

lsblk

Code:

anyone knows how to configure GRUB2 to unlock the OpenSUSEMixCryptBoot partition and load the kernel ?

Do you have the openSUSE containers listed in the Mint crypttab ?.

Darkyere · 01-25-2017, 04:20 AM

Its not a question about Mint being able to unlock OpenSUSE containers from mints perspective.

Its a question about making GRUB2 unlock OpenSUSE boot when i try to boot OpenSUSE through GRUB2.

Ty for your response btw i highly appreciate the input

Really ?.
Which system built the grub boot code ?.
Which system built the initrd ?.
Which system determined what (initrd) hooks are active ?.

Things are rarely as straightforward as one might like.
I asked the question for a reason.

Mint build the Grub boot code

OpenSUSE builds its own initramfs
OpenSUSE determines which hooks is active in OpenSUSE own initramfs

----

I though tried to add the OpenSUSE container's to /etc/crypttab and ran update-initramfs -u. they are now unlocked at boot now.

I rebooted and unlocked the containers.

Then i ran update-grub and grub-mkconfig

When in GRUB2 i choose OpenSUSE to boot it still fails.
Tells me it wants to unlock the / system and not the boot

But thanks again for trying
