More info: Plugged in another box (running a fresh install of PCLinuxOS, 
another systemd-free distro) I get df and fdisk to give me the proper size 

While there I reformatted the drive to fat32; plugged it back in the Devuan 
box, fdisk still gives the wrong size, and still tells me it is ext4...
