So, we currently clean up names here a bit too drastically. That said, I am a bit uncertain about the whole fqdn-as-kernel-hostname thing. That's a concept that only makes sense on single-networked hosts, and mingles protocol-specific semantics of DNS with a very generic concept. Or to put this differently: I am pretty sure gethostname() should return something that is useful for mDNS, for Bluetooth host names, as well as per-interface hostnames. i.e. "foobar" should appear as "foobar.local" on mDNS, as "foobar.waldo.com" on eth0, and as "foobar.quux.net" on eth1, as well as just "foobar" on Bluetooth. But if the fqdn is used in gethostname() then suddenly all this makes a ton less sense, on mDNS we'd have to shorten things, on some interfaces might now match 1:1 but on others not at all anymore, and Bluetooth suddenly sees IP pecularities spill into its BT host name. I am aware that many systems use fqdn as hostnames, but this doesn't really sound like something we should advocate, as it it only makes sense within very specific networks. Currently, "hostnamectl set-hostname" won't accept it at all, but you can write it manually to /etc/hostname. I am figure "hostnamectl set-hostname" is currently a bit too drastic, but I am not fond at all of the idea of adovcate this fqdn-as-kernel-hostname nonsense any further, it sounds like the wrong idea, from a very narrow IP+DNS mindset... > $ cat /etc/hostname > korathmydomaincom > > $ pacman -Qi systemd | grep Ver > Version : 197-4 > > At a suggestion from my distro's discussion forum, manually editing > /etc/hostname and putting the FQDN back in there works.
