These entries do not normally exist in the dict. The entries from the latest mock config are:

config_opts['plugin_conf']['sign_enable']
config_opts['plugin_conf']['sign_opts']
config_opts['plugin_conf']['sign_opts']['cmd']
config_opts['plugin_conf']['sign_opts']['opts']

@tkopecek just curious, will this properly record things in koji's sign functionality? Like list-signed and such will work?

I'm afraid, that not. It will behave like bare rpm, so it will skip the add_rpm_sig phase. Need to test, what mock's plugin will really create and maybe update the import_rpm method.

Ok, I've fixed one bug and tested that it will correctly parse/save signatures.

Thank you @tkopecek. Will this be pulled forward to the next Koji point release?

Yes, it is scheduled for 1.22 (not 1.21.1 as it is behaviour-changing patch)

:thumbsup: for the code
I think it is better to add some notes in doc to indicate that this does nothing to the sign functions of koji

note added
