I can't view LP:2015363. But AIUI, lunar's kernel has surpassed the kernel size limit for this platform, so this seems like really the only viable option at the moment.

I'd just suggest that the commit message describe more of the "why", given that readers like myself may not have access to the bug for context.

This was discussed on MM between myself, Dann and Adam.
The latest lunar maas images are unusable due to https://bugs.launchpad.net/cloud-init/+bug/2009746. Maas image builds are failing due to a size check for these xgene systems (the kernel since moving to 6.2 has grown too large). I feel it's reasonable to drop xgene systems for now to get a working image out for release day.

Assuming this is just removing the xgene flavor for lunar, I'm +1.
