[Samba] Change machine name without a reboot?

[L.P.H. van Belle]

Wasn't systemd using the following order. 

1) config from /lib/systemd/... etc..  
2) override config with /etc/systemd/...  etc ..  

And to add a unit file snippet, which can be used to append or 
override settings in the default unit file, simply use : 

systemctl edit smb.service
or 
systemctl edit --full smb.service

Edit creates the needed dir/files in /etc/systemd 
And adds a override.conf 


and reload 
systemctl daemon-reload 

done. ;-)
