Since it is an audio player, that can play mp3 files and other, which can be stored on mounted devices such as external harddrives or mounted network shares, it makes sense to allow the player to access these locations per default.
Please grant permission to auto-connect removable-media.
After several discussions between snapd architects, security, advocacy and other reviewers, we’ve updated our removable-media criteria in our processes.
Applying the new criteria to this request, sayonara is an audio player. https://sayonara-player.com/changelog.php lists its 0.3.2 release more than 7 years ago. I was unable to determine @tschlaeppi’s status within the sayonara upstream project.
@advocacy, can you vet the publisher using one of these criteria:
the snap’s (vetted) publisher is the upstream of the software
if the snap is published by someone other than upstream, the publisher must be vetted and either be an established committer to the upstream or the wider snap ecosystem (eg, an established well-known contributor to the software itself, a member of the snapcrafters group, etc)
