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@jailer ~]# glances

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.

That's why I have terribly outdated 13-CURRENT on bunch of servers and can't
update them.
Most of them look like this:
[tiger@st25]:~>zpool status
pool: st25
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
st25 ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
ada0 ONLINE 0 0 0
ada1 ONLINE 0 0 0

ada4 ONLINE 0 0 0
ada5 ONLINE 0 0 0
mirror-3 ONLINE 0 0 0
ada6 ONLINE 0 0 0
ada7 ONLINE 0 0 0
errors: No known data errors
They haven't separate boot device and have from 7 to 30+ Tb of data that I
can't backup anywhere for re-install server with disk partitioning. Some time
ago I managed to get aroud this reverting 2 commits ( r342151 + don't
remember revision) but then there where some other improvements after which I
lost the opportunity to revert this commits
