Public bug reported:
Hit this again today on 16.04 on a new system. Thought I'd reported this
but obviously not.
lxc-checkconfig erroneously reports:
Kernel configuration not found at /proc/config.gz; searching...
Kernel configuration found at /boot/config-4.13.0-37-lowlatency

17.10+ have the corrected version; it would be useful to get into 16.04.
