At this point, I think the second patch there is doing the right thing.
The reason I asked slangasek to NAC my upload was that poweroff wasnt' working
correctly.
The reason poweroff wasn't working correctly was that cloud-init is writing
'auto eth0' where cloud-initramfs-dyn-netconf is writing 'manual eth0'.
cloud-init's version means that ifupdown tries to bring the device down on
shutdown.

Status: New => Confirmed
** Description changed:
newer ifupdown versions (those in xenial) now keep interface state in
/run/network/ifstate.<interfacename> rather than combined in
/run/network/ifstate .
We need to update /lib/open-iscsi/net-interface-handler to write the
interface name into /run/network/ifstate.<interfacename> and then also
tear that down on down.
The failure can be seen when booting a maas image, if you first move the
included symlink out of the way:
- p="/etc/network/interfaces";
- [ -e "$p.link" -o -L "$p.link" ] || mv "$p" "$p.link"; cp "$p.dist" "$p"
+ p="/etc/network/interfaces";
+ [ -e "$p.link" -o -L "$p.link" ] || mv "$p" "$p.link"; cp "$p.dist" "$p"
(maas images ship with /etc/network/interfaces as a symlink to
../../run/network/dynamic-interfaces
and /run/network/dynamic-interfaces is populated by
cloud-initramfs-dyn-netconf).
+
+ This affects:
+ * cloud-init: cloud-init's fallback config currently writes 'auto' for the
network device. the cloud-initramfs-dyn-netconf writes 'manual', and so
ifupdown doesn't try to bring up *or* down the device.
+ * maas-images: the single difference from filesystem viewpoint from xenial
lxd image to maas image is 'ln -snf ../../run/dynamic-interfaces
/etc/network/interfaces'
+ * open-iscsi: the real need for open-iscsi's udev integration is to get the
resolvconf updates applied.
