 Posted: Tue Jan 02, 2024 2:57 pm Post subject: Dracut+Openrc+LVM on LUKS - Wrong password |
 |
|
Hi everyone, today I was testing for my project if the disk encryption with LVM work properly, and I tried to make an initramfs with Dracut.
So it's a system generated by the package manager I am making.
It's a system based on Openrc init system.
So my system is configured like that in a VM under VirtualBox:
/dev/sda1 (/boot/efi) FAT32
/dev/sda2 (/boot) BTRFS
/dev/sda3 (/) LVM on LUKS with 2 volumes, Swap and Root
The password is very simple, just 3 letters. And I checked, at boot the keyboard work properly, so the issue is not from the keyboard.
I generated the initramfs with dracut with the linux kernel 6.5.1, and I added the elogind support for the initramfs.
When I restart the VM to boot the new system, the prompt ask for the password, but even the password is right, it say it's wrong
Then, it show 2 errors:
| Code: | libgcc_s.so.1 must be installed for pthread_exit to work
Wrong password |
Linux kernel version: 6.5.1
Dracut version: 059
Openrc version: 0.52.1
I did a screenshot as well if you want to see: https://www.zupimages.net/viewer.php?id=24/01/f8r1.png
I generated the initramfs like that:
| Code: | | dracut --force --kver=6.5.1 |
In the dracut.conf, I added the required line for elogind (adapted to my system):
| Code: | | install_items="/lib/elogind/elogind-uaccess-command" |
And grub generated the grub.cfg with the disk encryption enabled.
Let me know if you need information.

What do you mean? That you added GRUB_ENABLE_CRYPTODISK=y to /etc/default/grub?
Can you please post the /boot/grub/grub.cfg? |

Yes it's what I mean.

I find how to do.
I had to add one more file apart of the one for elogind to the dracut.conf:
| Code: | | install_items=" /lib/elogind/elogind-uaccess-command /usr/lib/libgcc_s.so.1 " |
Is it normal dracut didn't include it ?

| The option "GRUB_ENABLE_CRYPTODISK=y" is not needed, because your /boot is not encrypted. And in your /boot/grub/grub.cfg are no traces that the Grub module "cryptodisk" is loaded. |

This option is definitely needed. It's not my first installation of an encrypted system.
And it's loaded.
As I said in my previous message, I solved the problem. The initramfs just missed one file: /usr/lib/libgcc_s.so.1
I find the solution. But thank you very much
