Comment 4 for bug 1629972

+ExecStop=/bin/sh -c 'for f in "$@"; do [ -e "$f" ] || continue; echo "$f existed."; exit 1; done; exit 0' -- /run/initramfs/open-iscsi.interface /run/network/network-root-fs
 ExecStop=/sbin/ifdown -a --read-environment

This will leave networking.service in "failed" state on stop -- *if* you do this hack, then please just put it into the existing ExecStop= line, and simplify this:

 ExecStop=/bin/sh -c '[ -e /run/initramfs/open-iscsi.interface /run/network/network-root-fs ] || ifdown -a --read-environment'

However, this is still a nasty hack. Why would ifdown shut down the interface in the first place? If you use iSCSI, then /e/n/i should *not* have a "dhcp" stanza (and an "auto enXXX) for that interface, but a "manual" one, so that the declaration and behavior don't fight with each other.

I. e.:

 - If ifdown downs a "manual" interface, then let's fix that properly.
 - If /e/n/i still has a "dhcp" declaration, then drop that (I thought that got fixed ages ago already).
