Changing VIRTUAL-RUNTIME_init_manager for initramfs image

Changing VIRTUAL-RUNTIME_init_manager for initramfs image

[mar.krzeminski]

Hi,

I have machine and in this machine I have two images. One of this images 
is image for kernel initramfs.
In this image I want to change init manager to busybox mdev, while ine 
the other one I use udev.
I can do that by changing VIRTUAL-RUNTIME_init_manager variable.
And now is time for dummy qestion, but I am not sure, if I change this 
variable
in particular image everything will be ok? Is this a proper way to do so?

Regards,
Marcin

Yes, you can have a default assignment in your distro configuration, and
have another assignment in the image recipe that you want to have a
different init manager.

Also, don't you mean _dev_manager for the udev/mdev choice?

No, I don't think you can, since these are controlled from packagegroups, not 
the image recipe. It's certainly possible to create an initramfs image where 
you don't actually use those packagegroups and therefore you can just select 
the desired init system package directly.

Cheers,
Paul
