|
After a few years I've decided to come back to the Gentoo Land. In the meantime I think that a lot a things become ... complicated?
I'm struggling for few hours with a simple boot scenario, where I'm trying to boot up from a root on LVM, which is inside encrypted LUKS partition.
| Code: |
➜ ~ lsblk -o name,uuid
NAME UUID
nvme1n1
├─nvme1n1p1 A84A-289B
├─nvme1n1p2 a92c1ffa-0a85-46dc-963d-f2751b410ad7

So I'm trying to decrypt the "95d8c7f8-7744-4806-9e7f-448199f71be2" and boot with bc48d2d2-2282-48a7-ba3d-feb19abdcd73 as a root. The nvme0n1 contains my Arch installation.
Here is my /etc/dracut.conf file
| Code: |
add_dracutmodules+=" crypt dm lvm rootfs-block "
kernel_cmdline+=" root=UUID=bc48d2d2-2282-48a7-ba3d-feb19abdcd73 rd.luks.uuid=95d8c7f8-7744-4806-9e7f-448199f71be2 " |
And my /etc/default/grub
| Code: |
GRUB_CMDLINE_LINUX="rd.luks.allow-discards root=UUID=bc48d2d2-2282-48a7-ba3d-feb19abdcd73 rd.luks.uuid=95d8c7f8-7744-4806-9e7f-448199f71be2"
|
During boot I've encountered this failure:
| Code: |
dracut-initqueue[478]: Failed to start systemd-cryptsetup@luks\x2d3bdfab60\x2de423....service: Unit systemd-cryptsetup@luks\x2d3bdfab60\x2de423....service not found
|
It seems that it is trying to start using "nvme0n1p2 3bdfab60-e423-4c1d-97b0-a4d7aa92a7a2", which does not make any sense
I've tried to use ugrd and... without success

Am I missing something? |
