If you lock the door, you could run into trouble, if the studio catches
fire and btw. it's a safe bet that somebody will knock at the door. The
only safe solution is to ban people from the radio station who have no
business in the radio station and ask all people who are needed for the
production, to come to work.
Accidents will happen easily to everybody of us.
For Linux you should ban every piece of software, resp. all settings
that could cause issues and start all software with correct settings
that are needed. I suspect OOTB no distro will be perfect, but a lot of
optimization can be done by scripts to start a session.
On another list there's somebody who call people idiots that are unable
to follow his work flow, e.g. if people won't add a user to the group
audio manually, OTOH he blames a software for killing his speakers, just
because he was careless.
Taking care does mean to expect something that shouldn't happen. In
Linuxland we have a situation where a group of experts will blame users
if they just want to use a tool. The approach of Linux is that we need
to be toolmakers too. Btw. a lot of stuff that should make live for
users easier, made the usage harder instead.
A balancing act regarding to the realtime group issue isn't worse the
effort. Newbies should use a pre-build audio distro where the first user
already is member of the group audio and for a radio station where the
DAW has got several user accounts, there should be an audio engineer
being able to be admin.
