Fedora 24 Lxc Multiple /dev/pts Instances: Missing

If you are finding that when you run lxc-checkconfig then you will probably get output like:


Kernel configuration not found at /proc/config.gz; searching...

Note : Before booting a new kernel, you can check its configuration
usage : CONFIG=/path/to/config /usr/bin/lxc-checkconfig


The good news is that the error about dev/pts is a false alarm.

Apparently, more up to date Kernels don’t have a kernel flag that is clearly being used by lxc-checkconfig

However I can confirm that lxc seems to be working fine on Fedora 24
