Hi,
after I updated this morning my tinc vpn setup stopped working.

After poking around a bit I found that the tinc.service file sets PrivateDevices=true as part of the Systemd hardening effort (bsc#1181400)
If I set it to false tinc can access /dev/net/tun.
Why is this failing only now? The tinc Package was last changed a year ago.
Is it safe to set PrivateDevices=false or is there another way?
cheers
Wonko
