The real solution would be to make wise usage of LVM, for example by
allocating 100% of the extents at the beginning (or even dm-thin)
using filesystems where a shrink is supported (I'm here blaming xfs
for not having this, while ext4 has).
Leaving space unallocated doesn't gain us anything because the user
still has to manually resize both logical volumes and the partitions
inside them. Our default needs to be something that doesn't require
users to resize partitions.
