Right so the no-swap warning comes after partitioning scheme is
finalised, but before swapfile is created and activated.

I still want to default to having some swap. But have that provided
via swap partition, or a swapfile. So far my scripts are a bit hackish
as the swapfile does not form part of the parted aware things /
something one cas specify in partman-auto recipes. It really is tucked
on the side, in finish.d, at the moment.

I have no solution yet for e.g. partman-auto automic recipe which uses
swapfile, if the rootfs filesystem is ext4; but creates a swap
partition if the rootfs filesystem is btrfs. And i'm not quite sure
how to express that in the recipe, or decode it.
