Description

Symptom
/etc/resolv.conf is overwritten by dhclient:

    # cat /etc/resolv.conf 
; generated by /sbin/dhclient-script
search nethesis.it vboxnet0.tld
nameserver 192.168.5.252

dhclient is running with -1 option (see #2057#note-4) 

    # ps -C dhclient -o command | tail
COMMAND
/sbin/dhclient -1 -q -lf /var/lib/dhclient/dhclient-eth1.leases -pf /var/run/dhclient-eth1.pid eth1

Reproducibility

Expected behaviour
/etc/resolv.conf contains the result of the template expansion

The bug was already fixed in nethserver-firewall-base, and was re-introduced when the network UI module was moved from nethserver-firewall-base to nethserver-base.
See commits nethserver:nethserver-firewall-base|aa781dd2 and nethserver:nethserver-firewall-base|efdc4b76.

Lost fixes are now been moved to a special action called interface-config-adjust, executed in interface-update event, just before expand-template.
