Kernel crashes at this point.
It does not crash if I start the container as privileged.
- kernel used is 4.0.4-040004-generic from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.4-wily/
The issue was a bit weird:
- I've updated the kernel to 4.1-rc6, no longer crashing
- still, the container was not starting on 4.1-rc6
- it turned out that "lxc-create -t download ..." created the container
with all files being 0-bytes for some reason (so, 0-byte /sbin/init and
all other files being 0-byte)
- "exec file format" (0-byte /sbin/init) was causing 4.0.4 kernel crash?
Anyway, problem solved.
