Also exist additional issue, if we add system static host-mapping all dhcp records will be erased.

vyos@vyos-rtr01# sudo cat /etc/hosts

# From DHCP and "system static host-mapping"
100.64.255.102	 ubuntu	 #on-dhcp-event 0:c:29:e3:86:1d

add static-mapping record

vyos@vyos-rtr01# set system static-host-mapping host-name Test01 inet 100.64.255.120
vyos@vyos-rtr01# commit
