[Bug 1881588] Re: pre-seeding lxd on Core appliances breaks console-conf user creation

[Stéphane Graber]

Yeah, the new logic should work fine.

An alternative for the older logic would be to skip uid < 1000 so we
ignore system users.

Applying something like this worked 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 ...
