Nope - in my system's current state, when rebooting into 4.19 there's
no /dev/mapper symlink, but when rebooting into 4.18 there is. I've
gone back and forth several times, and the behavior is consistent.
There's clearly something that 4.19 is doing differently from 4.18. [I
guess it might still be a udev bug, which is being exposed by some
change in 4.19.]
