Hi,
When i compile a non GENERIC kernel (which mainly removes some debugging and devices i do not have) the Python program glances fails with the following message.
[root at jailer ~]# glances
Traceback (most recent call last):

FreeBSD jailer.local 12.2-STABLE FreeBSD 12.2-STABLE r366936 JAILER amd64
I don't understand what is breaking it as everything else works fine and i only removed the usual stuff i do. Below is the custom kernel config.
Thanks.
