While I was initially trying out Rune, via a wired connection I was able to resolve other machines in my network by name, including the server that holds all my music.
After switching to a Wi-Fi connection, the mount for my music failed. Eventually traced it down to a /etc/resolv.conf that only contained the default Google nameservers. Although in one of the many attempts, I thought I did see my own nameserver once, but could be mistaken as I was switching between wired and wireless lots of times.
Could this solely due to no configuration file for wlan0 network file being created under /etc/systemd/network/, because after manually creating one, I now get a correctly configured /etc/resolv.conf for my local network. Or could it be a timing issue and I've just been lucky on the last few attempts.
BTW the DHCP setting in /etc/systemd/network/eth0.network is set to: both. According to the man page, this shoul be "yes", "no", "ipv4", or "ipv6".
Cheers.
