ok, answering myself again:

https://github.com/lxc/lxd-pkg-snap/blob/latest-
edge/snapcraft/commands/daemon.start#L192

which simply calls:

chroot /var/lib/snapd/hostfs/ \
  useradd --system -M -N --home /var/snap/lxd/common/lxd \
  --shell /bin/false --extrausers lxd || true

i dont see how the system can end up managed here ...

  pre-seeding lxd on Core appliances breaks console-conf user creation

Bug description:
  when seeding appliance images with lxd, user creation gets impossible.

  console-conf skips the user creation, system-user assertions do not
  work either because there is already a user exisiting in the image.

  the tty screen shows instructions to log in with "lxd@<IP ADDRESS>"
  ...

  since the lxd user is a special case hack in Ubuntu Core images, "snap
  create-user ..." should probably learn to ignore its existence ...
