Comment 1 for bug 1806777

It seems the option to restore cloud-init functionality to setting the iscsi root device interface to ifupdown 'auto' dhcp would lead back to the hang-on-shutdown.

Possibly another way to address this would be to update klibc's ipconfig to update the /run/net-IFACE.conf file with the dns search domain it gets. I will look at that; i can't think of any problematic side effects of ipconfig updating that specific field in the conf file without changing anything else. open-iscsi always sets it to an empty string, since it is per-spec impossible for ibft to ever provide a dns search domain. I shoudl check the possibility of static root iscsi config built-in to the initramfs as well, in case that might contain dns search domain that ipconfig shoudl not overwrite.
