I recently used do-release-upgrade to upgrade my Lenovo T470 from
[x]ubuntu 23.04 to [x]ubuntu 23.10.
It's working OK but permission changes on the /run/NetworkManager
directory have broken one bit of customisation. The permissions on
/run/NetworkManager used to be:-
chris$ ls -l /run
total 36
drwxr-xr-x 5 root root 140 Dec 15 16:24 NetworkManager
srw-rw-rw- 1 root root 0 Dec 15 13:20 acpid.socket
-rw------- 1 root root 0 Dec 15 13:20 agetty.reload
drwxr-xr-x 2 root root 40 Dec 15 13:20 alsa
drwxr-xr-x 3 root root 80 Dec 15 13:20 apache2
drwxr-xr-x 2 avahi avahi 80 Dec 15 13:20 avahi-daemon
...
...
Now they are:-
chris$ ls -l /run
total 36
drwx------ 5 root root 140 Dec 15 16:24 NetworkManager
srw-rw-rw- 1 root root 0 Dec 15 13:20 acpid.socket
-rw------- 1 root root 0 Dec 15 13:20 agetty.reload
drwxr-xr-x 2 root root 40 Dec 15 13:20 alsa
drwxr-xr-x 3 root root 80 Dec 15 13:20 apache2
drwxr-xr-x 2 avahi avahi 80 Dec 15 13:20 avahi-daemon
...
...
Can anyone tell me where these permissions are configured, or even if
they are 'configured' at all and not just set by code in NetworkManager.
I use the file /run/NetworkManager/no-stub-resolv.conf in my dnsmasq
configuration so it needs read access to that dirctory. It's the
different upstream DNS server I need, when on my home LAN dnsmasq uses
the LAN DNS server but when away from the LAN it gets the DNS servers
provided by whatever means Im using to connect to the 'net.
Alternatively is there a simple way to find out (as NetworkManager
does) what upstream DNS server to use?
