I see you went the sudo way. The (minimal) audit that was conducted
before deciding this solution was safe must be documented somewhere.

For this solution to be safe, I think the sudoer credentials should be
limited to the setupcon command, *without* command line arguments, at
least to avoid the use of --force that more or less triggers a DoS.
See the section about Cmnd_List in sudoers(5) for how to implement
this using "" in place of the arguments.
