My point is that all of these need some way to handle configuration and inheritance, and I don't think that a bunch of per-task prctls is the right way. As just an example, saying that interactive users can autoload modules but other users can't, or that certain systemd services can, etc, might be nice. Linus already complained that he (i.e. user "torvalds" or whatever) should be able to profile the kernel but that other uids should not be able to.Neat, maybe this could already be achieved with this interface and systemd-logind, "ModulesAutoloadUsers=andy" in logind.conf where "andy" is the only logged-in user able to trigger and autoload kernel modules. However maybe we should not restrict too much other bits or functionality of the other users, please let me will follow up later on it.quoted
I personally like my implicit_rights idea, and it might be interesting to prototype it.Andy following on the idea of per user settings, I'm curious did you manage to make some advance on how to store the user settings ? the user database format is old and not extensible, there was cgmanager or(v2 is under very very early consideration, would love to stay in the loop as this is considered)
For user database I'm not aware of any code, but it seems that if the database or settings are adapted to today use cases then systemd-logind may use them. Yes if there is something I'll Cc'you.
