Fedora 24 Lxc Multiple /dev/pts Instances: Missing
Sep 14, 2016 · 1 minute readCategory: lxc
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...
Kernel configuration found at /boot/config-4.7.3-200.fc24.x86_64

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
