Re: [arch-general] grub2 + luks + keyfile
Seems I forgot to add the usb hook. It works now. Thank you for replying and directing my attention towards mkinitcpio.

The grub2 wiki page specifies that in order to decrypt the root partition, the following should be added in /etc/default/grub: Just to be clear, it's the mkinitcpio encrypt hook that's reading the keyfile, grub2 seems to be configure just fine (so far). GRUB_CMDLINE_LINUX=cryptdevice=/dev/sda2:root Also an earlier version of the luks wiki page, that was intended for grub-legacy, mentioned that to decrypt the root partition using a keyfile, the following kernel parameter has to be added: cryptkey=/dev/disk/by-uuid/uuid:vfat:/keyfile So I've attempted to add both of these parameters in /etc/default/grub: GRUB_CMDLINE_LINUX=cryptdevice=/dev/sda2:root cryptkey=/dev/disk/by-uuid/3848-EFD5:vfat:/keyfile I've also added the encrypt hook and vfat module in /etc/mkinitcpio.conf. I don't remember if these are exempt from autodetect. You can try lsinitcpio /boot/initramfs-linux.img | grep fat to verify that it's on there. I think there's also a fat module which is needed by vfat, I don't know if mkinitcpio pulls in module deps as well. You can also try the fallback image. This is displayed while booting up: :: running early hook [udev] :: running hook [udev] :: Triggering uevents... :: running hook [encrypt] Waiting 10 seconds for device /dev/disk/by-uuid/3848-EFD5 ... Keyfile could not be opened. Reverting to passphrase. I know that message kind of looks like the device is not found, but it's likely a problem with mounting the filesystem. The usb flash drive is formated with mkfs.vfat and contains just the keyfile. I would greatly appreciate any advice.

Now i have found an irritating thing it seems it doesn't like xfs and the ususal xfs_freeze hack from grub1 is not working anymore. Does anyone already use grub2 with xfs and if yes how did you solve this issue.

Personally i prefer isolinux as a better solution for ISO bootloader, but grub's advantage is the grub shell... From what you write here, it seems that you can access the CD drive through another than the BIOS boot device method. It doesn't matter that access is slow, it only matters that we are able to load the kernel and initramfs on a greater number of machines. IMO, this is worth looking into. You get these ata0, ata0,1, ata1 devices when adding the ata module to grub2 image. But the problem is: No one could say on which bus the users cdrom is (ata1, ata3,...). So the boot ends always in a grub2 shell instead showing the menu. User then must set it per Hand, like: set root=ata1 linux /boot/vmlinuz26 initrd /boot/kernel26.img boot And I've tested this ata method only on VMs. I'm not sure if on real machines the cdrom is realy detected as ata device (it wasn't detected as normal device cd0, cd1 on real hardware if using the biosdisk module). And i realy don't know why, on virtualbox,qemu it work's. If one would test - the way to make a grub2 bootloader image for mkisofs is: grub-makeimage -o mycore.img list_of_modules cat /boot/grub/cdboot.img mycore.img myboot.img myboot.img could now used as mkisofs parameter (-b) like we does it with grub-legacy in mkarchiso. Grub2 modular design (and the available modules) have a great potential IMHO (not only that one could make it terrible blinking and colored, splash shit). But there is a lack on documentation IMHO Gerhard
