Comment 21 for bug 1881588

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 ...
