Comment 7 for bug 1755858

I have a test branch and build
+ * make iscsid socket activated to only activate it as-needed (LP: #1755858)
+ - debian/open-iscsi.socket: systemd socket file for iscsid
+ - debian/open-iscsi.service: do not start or check iscsid.service
+ - debian/rules: install and enable iscsid.socket
+ - debian/patches/iscid-conf-use-systemd.socket-patch: default to the socket

Building in ppa [1] now.
It is not yet up for final review, but feel free to take a look at [2]

I Won't have time for it anymore for a bit, some tests on the ppa (upgrades and how they affect it as well as new installs - since it is there by default the latter meant purge+ppa+install).
