Note that running that stuff past audit2allow is how I hit https://bugzilla.redhat.com/show_bug.cgi?id=1328956 , so that may also be relevant. I think rkt right now will only work without overlayfs. Since overlayfs does not properly support SELInux labeling. Ah, OK; yes, it works fine with --no-overlay (running as root/unconfined_t). While it seems implausible, let me know if there's anything I can do to help. FWIW, here's the AVCs I get in that case (launching rkt as root/unconfined_t, dontaudit off, setenforce 0 (although note that it works just fine with setenforce 1 AFAICT, that was just to get AVCs)):

None of these seem to be causing any serious issues, and systemd is in fact running in the container.
This is a kernel issue, which we have existing bugzilla for it. https://bugzilla.redhat.com/show_bug.cgi?id=1178944 *** This bug has been marked as a duplicate of bug 1178944 *** I find it mildly annoying that the only non-duplicate bug in that chain, I can't actually see (Access Denied), so I've no way to get notified when it's fixed. ... Also, Firefox helpfully "remembered" that I'd closed a previous bug as NOTABUG, and made this bug one too when I commented. -____- Sorry about that. *** This bug has been marked as a duplicate of bug 1178944 *** Robin sorry about that, but be assured that if we get this to work and merged in to upstream kernel, we will make a lot of noise. |
I'm aware rkt support is a work in progress, so these may all be fixed somewhere, but: This is everything in my audit log with "dontaudit off", "setenforce 0" when running: rkt run
