** Description changed: + [SRU Justification] + On upgrade, some users who have selected a non-default setting for their clock handling in the installer will see prompts for a conffile they never edited by hand. + + [Regression potential] + Because we are adding a pre-dependency to a package, there is risk of this causing upgrade failures. The upgrade path should be tested aggressively with different profiles from both 14.04 and 15.10 before publishing to -updates. + + [Test case] + 1. On a newly-installed 14.04 system, edit /etc/default/rcS to contain 'UTC=no' instead of 'UTC=yes'. Make no other changes to this file. + 2. Enable -proposed in your apt sources. + 3. Run do-release-upgrade or update-manager to upgrade to 16.04. + 4. Confirm that the upgrade succeeds. + 5. Confirm that you are not shown a conffile prompt for /etc/default/rcS on upgrade. + 6. Confirm that /etc/adjtime has been created, with 'LOCAL' as the third line of the file. + 7. Repeat steps 1-6 for a newly-installed 15.10 system. + + slangasek | pitti: I see sysvinit Breaks: systemd (<< 228-5ubuntu3), but that doesn't enforce systemd 228-5ubuntu3 being configured before sysvinit, which means the conffile may already be migrated away before systemd postinst runs... I think the right way to do this is with initscripts Pre-Depends: systemd, and for initscripts' preinst script to handle any conffile cleaning so that users are spared conffile prompts on upgrade pitti | slangasek: ah, good point; this needs to be tested thoroughly, pre-depends have some habit of causing trouble See bug 1541532 and http://launchpadlibrarian.net/236311219/systemd_228-5ubuntu2_228-5ubuntu3.diff.gz and http://launchpadlibrarian.net/236367969/sysvinit_2.88dsf-59.3ubuntu1_2.88dsf-59.3ubuntu2.diff.gz
