fscreateoptions for additional partitions?

[IsaacJT]

Problem description

I'm trying to work around an issue with creating XFS filesystems in a new userspace (Ubuntu 23.10) running an older kernel (5.4, as that's all the build environment supports) where mkfs.xfs in 23.10 enables additional features that the 5.4 kernel does not support. I've resolved this for the root partition using the information from https://osinside.github.io/kiwi/troubleshooting/filesystems.html, but this does not seem to apply to the additional partitions, e.g.:

            <partitions>
                <partition name="home" size="512" mountpoint="/home" filesystem="xfs" />
            </partitions>

Is it possible to set this behaviour for the additional partitions, somehow? Adding fscreateoptions to the partition causes a schema validation error.

Expected behaviour

We can set fscreateoptions on the additional partitions in order to disable unsupported features.

Steps to reproduce the behaviour

Create an Ubuntu 23.10 image with an additional XFS partition using a 23.10 userspace but with the kernel from Ubuntu 20.04.

Hi Isaac, good point. We can certainly add that

Currently there is a lot on my plate, I can't make any promises when I get to it
