Re: Weird sys.fqhost value

Hi Bas,

thanks for trying to reproduce the error. The host is running on Ubuntu 
20.04. If I downgrade to Cfengine 15.2, then sys.fqhost is working 
correctly. As soon as I upgrade to Cfengine 18.2 or above, the error 
appears. There is no change on the configuration or the masterfiles between 
upgrading/downgrading.

<snip>
root@test1:~# *cat /etc/hosts*
127.0.0.1    localhost
127.0.1.1    test1.example.com test1

::1        localhost ip6-localhost ip6-loopback
ff02::1        ip6-allnodes
ff02::2        ip6-allrouters

root@test1:~# *cat /etc/hostname *
test1

root@test1:~# *cat /proc/sys/kernel/hostname*
test1

root@test1:~# *echo $HOSTNAME*
test1
</snip>

I have absolutely no idea where redundant space characters are coming from. 
This is so weird.
