iscsiuio ships iscsiuio.service but not iscsiuio.socket

[Benjamin Drung]

Imported from Debian bug http://bugs.debian.org/1056733:

/lib/systemd/system/iscsiuio.socket seems to be missing from the iscsiuio
package. The open-iscsi packages ships iscsid.socket and iscsid.service on the other hand.

This blocks running some upstream dracut test cases: https://github.com/dracut-ng/dracut-ng/issues/446

Benjamin, are you planning to work on this?

Benjamin replied the following on IRC:

<ahasenack> bdrung: hi, are you planning on working on bugs.launchpad.net/ubuntu/+source/open-iscsi/+bug/2072484 ?
<bdrung> ahasenack, not currently. I would be happy if the server team would work on it.

[Andreas Hasenack (ahasenack)]

Would this inclusion suddenly make the service socket activated, and have other implications?

[Benjamin Drung (bdrung)]

Maybe. That change should probably tested.

I had the chance to try a system which has the socket and it was working fine.

It also is present in the rpm world, which implies that we'd not become the odd one adding it as the only distro.

What is left is finding the time to
1. add it to the PKG
2. try if then the default state at boot is as it should (or if it needs some dh_install... changes in d/rules)
3. find which use case gets to uip_connect in usr/iscsid_req.c as that is what will connect to the socket to see if the thing spawns
