I meant creating the group in %post (not editing a file owned by
firstboot). But the problem of assigning group membership still remains.
Alternatively, we could package something which gets kicked off via
xdg/autostart that could detect this and request sudo priveledges to add
the X user to the group. All really messy and too late now.
There is a package realTimeConfigQuickScan which potentially could be
kicked off at start, but having it persist post first log in is really
annoying.
So yes, we have two problems to solve here the liveuser and the
installed user. liveuser is OK - the installed user is not. How do other
packages handle this? How can a package know to give a particular user
group membership? I can't see a way out of this without user intervention.
For F19 I will submit the firtboot patch based on the config file and
see if I can make a good case for it.
If we do make changes to packages to fix these issues (not specifically
this issue), how can we ensure that the updates are part of the final
buildroot (and not only in updates)

Okay, I think Brendan has answered the 'why'. I suspect what we need
to do is check what needs access to those groups. For real-time
privileges it may be that the plugins working with jack need them, or
it might be that just jack does. I'm not sure either what access the
audio group is used for, I think for Jack it may be priorities rather
than just the old purpose of access to audio devices (which pulse for
example now solves through the seat idea afaik). Will check the limits
file Brendan mentions when I get time.

Basically processes run with this group are subject to priority
escalation as described by limits.d file in the
jack-audio-connection-kit package. This is a real concern for audio
users. Another use case for a firstboot patch is the pulse-rt group,
although I'm unsure of the implications.

It basically is a check to see if the logged in user can do all it needs
for "optimal" audio. By itself it does nothing, does not even need root
privileges to do these checks

Short of adding every user to said package, I agree (and think that is
no solution). I think you an Ian may have something with the seat/polkit
idea.

Sorry, perhaps I wasn't clear. Something like groups=... in the
firstboot config file, a programmatic solution rather than our hack.

Yes - there are two really important points to consider (correct me if
I' wrong here team) everything else can go by the wayside #1 is audio
group membership, number #2 is threadirqs
A VERY nice to have is the themeing because artists tend to be a select
bunch and first impressions count for something. Without the themeing I
guess the kickstart is ready. I can't see why adding the /etc/skel stuff
to a package helps anyone. If anything it adds unexpected config changes...

Meeting tonight 23.00 UTC
by Jørn Loamx
Morning/afternoon all
There will be a short meeting tonight on IRC (#fedora-audio on freenode)
at 23.00 UTC. I will create and add to the agenda on the wiki[1]
throughout the day. Anyone can add to it if the want too. I'm sorry for
the short notice, but hopefully as many as possible can make it.
If there are any questions, don't hesitate to take contact :D

I cannot see any other package owning these files, so I can add them to
fedora-jam-kde-theme.

Is there a right way to do this? I tried to find one but I couldn't see
an option in kickstart to make this happen. I could probably provide a
patch to firstboot (I think this would be really useful) but obviously
it will be too late for this release. Or is this something which should
go into pam or somewhere else?
Alternatively we could add this to %post in jack-audio-connection-kit
but I'm not sure if this is considered safe in a critical-path package

Thankyou! Hopefully all the changes you've requested should be done by
Wednesday.
I think the notifications system in the wiki is suspect and is probably
something that needs attention. I should raise a ticket
