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
value.
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...
Cheers,
Ron.
