[SOLVED] Dracut info

tuxuser1 · 05-21-2024, 03:47 AM

Hi,

I tried to ask to dracut devs but nobody answer.
Github repo and chat seem dead.
Do you know whether possible to generate an initramfs specifying a different root dir ?

Best regards.

Hi, you may set another /boot directory... I haven't tried this, and I apologise in advance if I'm off topic

-b directory

man update-initramfs

for a simplified view...

Code:

update-initramfs --help

Usage: update-initramfs {-c|-d|-u} [-k version] [-v] [-b directory]

Options:
 -k version     Specify kernel version or 'all'
 -c             Create a new initramfs
 -u             Update an existing initramfs
 -d             Remove an existing initramfs
 -b directory   Set alternate boot directory
 -v             Be verbose

See update-initramfs(8) for further details.

I hope this helps

By this do you mean something different from the root device, which is covered by man dracut? I copied the following directly from the dracut man page:

Code:

Specifying the root Device

           This is the only option dracut really needs to boot from your root partition. Because your root partition can live in
           various environments, there are a lot of formats for the root= option. The most basic one is root=<path to device node>:

               root=/dev/sda2
...

What is the situation that lead to your question?

Update-initramfs has nothing, other than similar end result, to do with dracut.

You image to run a package manager bootstrapping into a folder.
I'd want to generate dracut image from that folder, searching the resources from that folder.
If that's impossible then chroot inside and generate the image should resolve it.

Chrooting has worked for me when necessary.
