Yes, I added the releases, not daily.

lxc remote add --protocol simplestreams ubuntu-minimal-daily https://cloud-images.ubuntu.com/minimal/daily

Yes; that's nice

systemctl mask does exactly what you're saying (symlink)

we use the pre-boot mask operation (your file push) that's not needed.

I'll update this PR with that.

The minimal feature is a separate PR now.
