short and long hostname confusion.

I am somewhat confused about hostname setting. I use systemd and systemctl apparently only accept short hostname.

[root@********* ~]# hostnamectl set-hostname test.thetests.org
[root@********* ~]# cat /etc/hostname 
testthetestsorg
[root@********* ~]# 

As you see, hostsnamectl remove the dots and considers it as a short hostname. However the hostname command suggests that the contents of /etc/hostname should be the fully qualified hostname (otherwise the -s option of hostname would be pointless). So what's the proper way the set the fully qualified hostname? I am on a laptop with a dynamic IP so I have not a real external hostname. What's the more reliable/proper way to configure the hostname?

Re: short and long hostname confusion.

This is expected behaviour, see "man hostenamectl". Not sure why you think /etc/hostname should contain the FQDN, "man 5 hostname" tells it shouldn't.

What's your goal exactly?
