--audit and shell=none

[rusty-snake]

Run firejail --profile=any-profile-that-has-shell_none --audit will end with
Error: shell=none configured, but no program specified. But it is not necessary to so specify a program if the profile is given with --profile and the program is never started because of --audit.

But it is not necessary to so specify a program if the profile is given with --profile

I never interpreted the --profile option to imply a program name, it just loads a specific profile. In other words I'd consider that specific command to always be a no-op because it lacks a command (an application) the user wants to have audited. Do you regard this as a bug? I do agree that the specific error message could be more informative.

--audit audits the profile. => If firejail knows the profile (by adding a program name or using --profile) it can audit the profile.

bug? yes.

Fix is in, you can try it out.
