/etc/bootc/kargs.d

It would be useful to have /etc/bootc/kargs.d in addition to /usr/lib/bootc/kargs.d get merged in.

Example use case: If you have a mixed hardware cluster, you often will have a different set of console args related to the serial console, but otherwise all the nodes are the same. You could make custom images for each hardware class, but if there was an /etc/bootc/kargs.d, you could just drop that arg in there and the same image would work everywhere.

We support conditionalizing kargs on architecture right now https://containers.github.io/bootc/building/kernel-arguments.html#usrlibbootckargsd

But yes per our discussion sometimes there are kargs that are dependent on (platform, arch) where "platform" is like "gcp", "aws", "metal" etc.

Yeah, where I usually have been seeing it though, the arch is x86_64. Just different serial ports. So, not too much to conditional on.

I will say that when using Anaconda to kickstart and install a bootc image, I was surprised it did not preserve the console argument from Anaconda automatically. pyanaconda parses the kernel arguments passed in through PXE boot and preserves the console argument when writing the bootloader configuration for a normal kickstart. I'm able to add the console argument manually with the ostreecontainer install by using the bootloader command and the --append argument.
