Description Martin Schröder 2023-06-24 15:18:29 UTC 
Since upgrading to 15.5, the df plugin (and others that rely on the output of the df command) omit some entries (like root and home).

Comment 1 Martin Schröder 2023-06-24 15:19:42 UTC 
Correction: / is reported, /home is not.
Comment 2 Martin Schröder 2023-07-07 14:09:39 UTC 
Cause: munin-node runs with ProtectHome=true.

Solution:
sudo systemctl edit munin-node.service

and add

[Service]
ProtectHome=read-only
