 |
|
Hello folks!
Previous time, I decided to encrypt my rootfs 
The problem is exactly initramfs. I don't know how that thing even works. I seen many youtube video, but unfortunately everyone guide is old and deprecated.
I used ugrd in this case, because is it the most simple way to do it.
I am getting massage on boot:
| Quote: | | EFI stub: Loaded initrd from command line option |
And later...
| Quote: |
VFS: Cannot open root device "" or unknow-block(0,0): error -6
Please append a correct "root=" boot option: here are the available partitions
103:00000 50001076608 nvme0n1
(driver?)
103:000001 nvme0n1p1
103:000002 nvme0n1p2
List of all bdev filesystems:
vfat
msdos
exfat
fuseblk
xfs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknow-block(0,0)
|
And what that all stuff means? I don't get it.
Nvme0n1p1 is boot partition. Nvme0n1p2 is encrypted.
Why ugrd is not even prompting me to specify password to unblock disk? This even makes no sens...
In nutshell:
1. I used gentoo wiki to set up kernel, rootfs, and ugrd
2. I mounted /boot and used 'make install'
3. efibootmgr --create --disk /dev/nvme0n1 --label "Gentoo3" --loader "kernel-6.6.62-gentoo" --unicode "initrd=initramfs-6.6.62-gentoo.img"

Gentoo is on systemd
Any suggestion to fix it? |

ugrd uses xz compression by default, you have this set:
| Code: | | # CONFIG_RD_XZ is not set |
you can either enable that in the kernel or you can disable xz compression in ugrd by setting
| Code: | | cpio_compression = false |
in /etc/ugrd/config.toml
