Still an issue on Rudder agent version 6.2.0~beta1 on Debian 10 (buster), on an unprivilegied LXC container running on Proxmox.

Output when running rudder agent update:

error: Cannot follow symlink '/proc/net/netstat'; it is not owned by root or the user running this process, and the target owner and/or group differs from that of the symlink itself.
error: Cannot follow symlink '/proc/net/route'; it is not owned by root or the user running this process, and the target owner and/or group differs from that of the symlink itself.
error: Cannot follow symlink '/proc/net/snmp6'; it is not owned by root or the user running this process, and the target owner and/or group differs from that of the symlink itself.

Output of ls -l /proc:

It still happens, and makes the "rudder agent update" command output the error message

error: Rudder agent policies could not be updated.
