** Description changed:

- Description
+ [Impact]
+ libguestfs cannot configure network on Bionic onward.
  
- supermin cannot configure network on Bionic onward.
- 
- This bug is a combination of supermin package and 
+ This bug is a combination of libguestfs/supermin package and
  /etc/dhcp/dhclient-enter-hooks.d/resolved script from systemd,
  present on Bionic onward.
  When supermin creates the appliance does chroot and executes its init script.
  If networking is enabled init will call dhclient sript to configure the 
network.
  
  On Bionic onward the make_resolv_conf function of dhclient_script is 
overwritten
  in /etc/dhcp/dhclient-eneter-hooks.d/resolved which before exiting restarts
- the systemd.resolved service. 
- However, this happening in chroot environment fails with 
+ the systemd.resolved service.
+ However, this happening in chroot environment fails with
  "System has not been booted with systemd as init system (PID 1). Can't 
operate."
  and network is left unconfigured.

+ [Regression Potential]
+ 
+ Minimal. The fix removes the /etc/dhcp/dhclient-eneter-hooks.d/resolved hook 
installed by systemd.
+ systemd is not used inside the appliance so it should not cause any 
regression.
+ 
+ 
+ [Other]
+ 
+ Affects B,C,D,E.
+ 
+ Upstream fix :

  Workaround
  
- 1) Assume that libguestfs is installed, if not : 
- $ sudo apt-get install libguestfs-tools
