I'm pretty baffled. I've successfully used runuser with F20 as the host
and F20 in the container. Something is different in rawhide. I even
tried downgrading util-linux in the container to the latest version in
F20 and I still get the same error, which leads me to believe it's not
util-linux at all. The docker version in rawhide is newer (I'm running
rawhide host and rawhide in the container), but I wouldn't expect that
to affect runuser.

I checked the status of selinux in the container and it was disabled,
so I don't think that's the problem. I then tried re-launching the
container in privileged mode (--privileged=true) and that didn't
change anything. The runuser command still prints "System error" if I
use it to do anything, even nothing.

I'm trying to run some docker containers and it appears the runuser in
rawhide isn't functional in the container:
# runuser
runuser: System error
I can run runuser in a physical system running rawhide however. These
same images created off of F20 containers worked fine.
Has anyone run into this? Any ideas?

I would guess it is potentially SELinux or /proc being readonly.
Put the machine into permissive mode to see if it is SELinux, (I
doubt it).
You could check with a priv container to see if /proc or capabilities ar
ethe problem.
Strange testing on rhel7 I see it working.
