How to grant the snap app access to the /dev/mem?

[ogra]

@lvpb

you still need to use “sudo your-snap-command”

yup, this is dealt with in:

Multiple users and groups in snaps

The previous (obsolete) discussion on the topic is here. To make the discussion clearer I was asked to start a new topic with the currently agreed to design so that we may work through any additional details. As such, I will copy the entire ‘Introduction’ and a description of the 4 use cases from the other topic, but leave the ‘Implementation Ideas’ in the other topic for historical reference. Introduction Today, snappy’s notion of users (and groups) is primitive: daemons run as root commands…

eventually we should be able to assign all gpio access to a certain group or have it grant access via udev-acl’s so you wont need sudo for your snap command anymore.
