I am facing the following bug while runnign guestfish on Ubuntu Bionic onward, 
where the network cannot be configured :

The actual problem is the combination of (a) supermin and the fact that it does chroot
and (b) a dhclient hook present in Bionic (/etc/dhcp/dhclient-eneter-hooks.d/resolved)
that overwrites the make_resolv_conf function of dhclient_script with one that 
in the end restarts the systemd.resolved service.
Being, however in chroot, the new make_resolv_conf function fails with 
"System has not been booted with systemd as init system (PID 1). Can't operate."
and the network is left unconfigured.

Although there is a workaround for this, I am seeking for a better solution.
I would like to ask you if this is the expected behaviour of supermin or something
that needs fixing.

Thank you in advance.
