[SRU] overrides in /etc

Hello Julian, or anyone else affected,

Accepted networkd-dispatcher into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/networkd-dispatcher/1.7-0ubuntu3.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I created three scripts:

(1) override in both /usr and /etc
(2) usr-only in /usr
(3) etc-only in /etc

doing "echo $0 >&2"

and then ran networkd-dispatcher with -T (triggering scripts for current state) to run them:

# networkd-dispatcher -v -TTTT
No valid path found for iwconfig
No valid path found for iw
INFO:Triggering scripts for last-known state for allinterfaces
INFO:Invoking '/etc/networkd-dispatcher/routable.d/etc-only' for interface eth0
/etc/networkd-dispatcher/routable.d/etc-only
INFO:Invoking '/etc/networkd-dispatcher/routable.d/override' for interface eth0
/etc/networkd-dispatcher/routable.d/override
INFO:Invoking '/usr/lib/networkd-dispatcher/routable.d/usr-only' for interface eth0
/usr/lib/networkd-dispatcher/routable.d/usr-only
INFO:Startup complete

As we can see, this passes our test cases:

1. /etc overrides /usr
2. etc-only is executed
3. usr-only is executed

The verification of the Stable Release Update for networkd-dispatcher has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

This bug was fixed in the package networkd-dispatcher - 1.7-0ubuntu3.3
