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.
** Also affects: cloud-init (Ubuntu) Importance: Undecided Status: New ** Also affects: cloud-init Importance: Undecided Status: New ** Also affects: maas-images Importance: Undecided Status: New ** Changed in: cloud-init Status: New => Confirmed ** Changed in: maas-images Status: New => Confirmed ** Changed in: cloud-init (Ubuntu) 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.
