Finally I could verify the fix works well and fixes the issue. We are building core18 image using the snap which has systemd from proposed.
Steps to validate: 1. build core18 snap using proposed > git clone -b master https://git.launchpad.net/snap-core18 > cd snap-core18 > sed -i -e 's/current/pending/g' Makefile > sudo snapcraft 2. prepare test > git clone https://github.com/sergiocazzolato/snapd.git > git checkout tests-validate-lp-1778936 > cd snapd > < copy the core18_18_amd64.snad to tests/lib/ directory > 3. run the tests > spread -debug google:ubuntu-core-18-64:tests/main/interfaces-hostname-control -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1778936 Title: please re-add Support-system-image-read-only-etc.patch Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Bionic: Fix Committed Status in systemd source package in Cosmic: Fix Released Bug description: [Impact] * core18 systems fail to update hostname * this happens due to /etc/hostname actually being a symlink to a file under /etc/writable/, adjust hostnamed to take that into account when trying to update /etc/hostname [Test Case] * run a core18 system, check that dhcp acquire hostname is correctly updated in /etc/writable/hostname [Regression Potential] * This is cherrypick of code that has gone missing since xenial. * There is no change of behaviour for the classic systems. * Currently, core18 systems simply fail to update hostname/machine-info files, thus the worst case is that they will still fail to do so. [Other Info] * original bug report The 16.04 version of systemd had a patch to support the read-only etc. For core18 we will also need this change because core18 is still not on a fully writable etc. I will attach a debdiff against the current bionic version of systemd.
