A possible gotcha for Server is if the user installs Docker,

upon running, all free extents in the VG are made into a dm thin pool.
I was imprecise when I wrote "On first boot, docker-storage-setup
turns those free extents into a thin pool LV." That implies it's an
LVM managed thin pool, which it isn't. It's only manageable by
dmsetup. This suggests some special handing for Server perhaps. Anyway
I found it really non-obvious when suddenly a bunch of free space was
gone and I couldn't manage it with LVM tools.
That tool could probably be made smarter.
