It seems, newest runc has some compatibility changes in cli arguments: rpc error: code = 2 desc = "oci runtime error: flag provided but not defined: -bundle" Any attempt to access container's filesystem exitst like this - cannot simply run docker run --rm -i -t debian:jessie bash After downgrade, everything is normal again.
CONFIRMED as reproducable here.
Confirmed, app-emulation/docker-1.11.0 should block >=app-emulation/runc-1.0.0
This should be fixed. The dependencies of stable docker were adjusted to exclude this version of runc.
