@mvo: Fedora switched in 2019: https://medium.com/nttlabs/cgroup-v2-596d035be4d7 Debian switched with systemd 247.2-2 https://tracker.debian.org/news/1204112/accepted-systemd-2472-2-source-into-unstable/
I was about to follow Debian in systemd, but I'm holding the switch back for now. Could you please provide a link where snapd's progress can be tracked? I plan keeping the current systemd default then for 21.04 to minimize disruption and give some more time for preparation, but I'd like to make the switch early in the 21.10 cycle to also have time to fix regressions by 21.10's release. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1850667 Title: cgroup v2 is not fully supported yet, proceeding with partial confinement Status in docker.io package in Ubuntu: New Status in lxc package in Ubuntu: Fix Released Status in lxcfs package in Ubuntu: Fix Released Status in lxd package in Ubuntu: Fix Released Status in snapd package in Ubuntu: In Progress Bug description: Systemd upstream switched the default cgroup hierarchy to unified with v243. This change is reverted by the Ubuntu systemd packages, but as unified is the way to go per upstream support should be added to all relevant Ubuntu packges (and snaps): https://github.com/systemd/systemd/blob/v243/NEWS#L56 * systemd now defaults to the "unified" cgroup hierarchy setup during build-time, i.e. -Ddefault-hierarchy=unified is now the build-time default. Previously, -Ddefault-hierarchy=hybrid was the default. This change reflects the fact that cgroupsv2 support has matured substantially in both systemd and in the kernel, and is clearly the way forward. Downstream production distributions might want to continue to use -Ddefault-hierarchy=hybrid (or even =legacy) for their builds as unfortunately the popular container managers have not caught up with the kernel API changes. Systemd is rebuilt using the new default and is available from the following PPA for testing: https://launchpad.net/~rbalint/+archive/ubuntu/systemd-unified-cgh The autopkgtest results against other packges are available here: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac /autopkgtest-eoan-rbalint-systemd-unified-cgh/?format=plain https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac /autopkgtest-focal-rbalint-systemd-unified-cgh/?format=plain lxc autopkgtest failing: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac /autopkgtest-eoan-rbalint-systemd-unified- cgh/eoan/amd64/d/docker.io/20191030_155944_2331e@/log.gz snapd autopkgtest failing: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac /autopkgtest-eoan-rbalint-systemd-unified- cgh/eoan/amd64/s/snapd/20191030_161354_94b26@/log.gz docker.io autopkgtest failing: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac /autopkgtest-eoan-rbalint-systemd-unified- cgh/eoan/amd64/d/docker.io/20191030_155944_2331e@/log.gz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1850667/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
