Plymouth MicroOS on RaspberryPI 4

[Orkan]

Hello!

I’m currently working on a side project and successfully running MicroOS on a RaspberryPI4, configured via Combustion.

I’m having trouble finding information on how to properly set up Plymouth on this device, it will be an appliance and I want to clean up the boot process with a Plymouth theme instead of the text information.

Found a guide to install and setup Plymouth but when selecting the theme with:

plymouth-set-default-theme -R <theme>

I get an error:

Regenerating initrd image ...
dracut[F]: No permission to write to /boot.

I guess this is not the correct way to do it on MicroOS with the immutable filesystem. I know how to edit and update grub on this machine but have no idea how to activate Plymouth themes from there.

Please help

@Orkan Likely need to run transactional-update run plymouth-set-default-theme -R <theme>

Not really sure it’s supported… plymouth that is…

Thank you! I will test it.

The command executes properly and something is changing the color of text in the terminal but there is no Plymouth boot theme when restarting.

It works, I just needed to disable systemd status reporting in the kernel cmd line, thank you!
