 Posted: Fri Jan 05, 2018 3:50 am Post subject: [SOLVED]BTRFS luks with bliss-initramfs fails to boot |
 |
|
With the help of a Russian Redhat forum I managed to get it working with genkernel.
package.use
| Code: | sys-boot/grub device-mapper
sys-kernel/genkernel cryptsetup |
Initramfs
| Code: | | genkernel --luks initramfs |
Genkernel 3.5.2.5 (~amd64) works fine.
fstab
| Code: | /dev/sda1 /boot ext2 defaults,errors=remount-ro 1 2
LABEL=BTROOT / btrfs defaults,compress=lzo,subvol=@ 0 0
LABEL=BTROOT /home btrfs defaults,compress=lzo,subvol=@home 0 0
LABEL=BTROOT /.snapshots btrfs defaults,compress=lzo,subvol=@snapshots 0 0
/dev/mapper/cryptswap none swap defaults 0 0 |
dmcrypt
| Code: | swap=cryptswap
source='/dev/sda3'
options='-c aes-xts-plain -s 512 -d /dev/random' |
blkid
| Code: |
/dev/sda2: UUID="c1beb440-7673-448c-9a32-3a43968489df" TYPE="crypto_LUKS" PARTUUID="ddb0274d-02" |
grub.cfg
| Code: | ### BEGIN /etc/grub.d/10_linux ###
menuentry 'Gentoo GNU/Linux' --class gentoo --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-75bd9d59-b687-4bda-9f85-60023750992$
load_video
insmod gzio
insmod part_msdos
insmod ext2
set root='hd0,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 1670b716-ca81-447c-b83d-dcb074e7$
else
search --no-floppy --fs-uuid --set=root 1670b716-ca81-447c-b83d-dcb074e7febd
fi
echo 'Loading Linux 4.15.0-gentoo ...'
linux /vmlinuz-4.15.0-gentoo crypt_root=UUID=c1beb440-7673-448c-9a32-3a43968489df ro dobtrfs rootflags=subvol=@
echo 'Loading initial ramdisk ...'
initrd /initramfs-genkernel-x86_64-4.15.0-gentoo |
Followed the Snapper guide for Arch.
| Code: | umount /.snapshots
rm -r /.snapshots
snapper -c root create-config /
mount -o defaults,compress=lzo,subvol=@snapshots /dev/mapper/root /.snapshots
chmod -R 750 /.snapshots |
/dev/mapper/gentoo becomes /dev/mapper/root when not chrooted.
btrfs-send does not work from the systemrescuecd beta 4. Have to boot the Arch installation usb for that. |

Update:
Works fine with bliss when using vault_0, and not your own name. Encrypted boot (subvolume) with keyfile works fine too.
| Code: | menuentry "Gentoo - 3.9.9-FB.02" {
linux /kernels/3.9.9-FB.02/vmlinuz root=/dev/mapper/vault_0 enc_drives=/dev/sda4 enc_type=pass
options="compress=lzo,defaults,noatime,autodefrag,subvol=tank/root" triggers=luks quiet
initrd /kernels/3.9.9-FB.02/initrd |

^ Is a better setup for snapshots. |
