We already create /dev/disk/by-uuid symlinks for DM devices which contain crypto-type as next layer (as identified by blkid). Also create /dev/disk/by-label symlinks as the labels can be defined for crypto-type devices too. Reported and fix suggested by: Patrick Plenefisch <simonpatp@gmail.com> See also: https://lore.kernel.org/lvm-devel/CAOCpoWfYjOVNJNt+cnOVXDHiDq2wRogTqBijcUoa7chqOLRa5Q@mail.gmail.com/
