 Posted: Tue Feb 18, 2025 5:18 am Post subject: [Solved] Dracut + crypt-gpg dm + systemd? |
 |
|
I use Dracut for a long time. I have encryped full root with LUKS2 and key at USB in gpg file. I use rd.luks rd.lvm parameters and crypt-gpg dm - dracutmodules.
For this I require systemd-cryptsetup module that require to install "sys-apps/systemd" package. https://wiki.gentoo.org/wiki/Dracut#List_of_modules
Gentoo now support choice:
- sys-apps/systemd: The historical udev code base was merged with systemd's in 2012, so installing any recent systemd version already provides an udev implementation. The corresponding daemon is named systemd-udevd.
- sys-apps/systemd-utils: A collection of systemd-specific split off for use with alternative init systems. It includes the udev program.
https://wiki.gentoo.org/wiki/Gentoo_without_systemd#The_udev_situation
Dracut developers says that they fully support OpenRC init system. But I can't make proper Dracut initramfs without "sys-apps/systemd" package.
Can you explain me why "sys-apps/systemd" required? Can we extract systemd-cryptsetup and place to sys-apps/systemd-utils for Dracut?

| I guess systemd is used for systemd-ask-password. |

If you're looking for an initramfs without systemd, ugrd is an option where "systemdless" is part of the design 
At this point dracut is largely built around systemd stuff

It looks to me like regular cryptsetup can be used just fine.

It was my mistake, specified wrong UUID for USB :
rd.luks.key=/luks-key.gpg:UUID=
So Dracut working with sys-apps/systemd-utils, virtual/udev for BTRFS + LUKS2 + GPG. Without kernel modules, without "add_drivers". Without systemd.
Tested for version "dracut 105"
| Code: | | add_dracutmodules+=" plymouth crypt-gpg dm " |
detected modules at run:
| Code: |
bash
shell-interpreter
drm
plymouth
crypt
dm
crypt-gpg
rootfs-block
udev-rules
base
fs-lib
shutdown

For asking password Dracut can plymouth if it is installed.
