Thanks Scott for fixing this! However, this is awkward to have in
systemd: it meddles with ifupdown's and open-iscsi's internals and has
open-iscsi specific knowledge which really belongs into open-iscsi
itself. I. e. open-iscsi should ship the counterpart of debian/open-
iscsi.iscsi-network-interface.upstart. Adding a task for this.

Title:
resolv.conf not updated correctly for interfaces configured in
initramfs
Status in open-iscsi package in Ubuntu:
Triaged
Status in systemd package in Ubuntu:
Fix Released
Bug description:
maas images utilize cloud-initramfs-dyn-netconf . The way this works is
basically:
* /etc/network/interfaces in image is a link to
../../run/network/dynamic-interfaces
* kernel command line 'ip=' convince the initramfs to bring up networking
using 'ipconfig'
example: ip=::::maas-enlist:BOOTIF
* ipconfig writes files in /run/net-*.conf for each interface it configures.
* cloud-initramfs-dyn-netconf module writes /run/network/dyanmic-interfaces
based on /run/net-*.conf files that 'ipconfig' creates.
end result is that after the move to real root,
/etc/network/interfaces should be a symlink to /run/ that ends up
having something like this:
| ## This file is generated by cloud-initramfs-dyn-netconf
| auto lo
| iface lo inet loopback
| manual eth0
| iface eth0 inet dhcp
| dns-nameservers 192.168.64.3
| dns-search maas
resolvconf seems not to be working as well as it should be. In vivid
(now using systemd), I have only the resolvconf header in the file.
in all other supported ubuntu releases, doing the above results in
functional resolv.conf via resolv.conf. Seen here from trusty:
| # Dynamic resolv.conf(5) file for glibc resolver(3) generated by
resolvconf(8)
| # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
| nameserver 192.168.64.3
