we don't usually do separate announcements for POM, the changes are usually not that big there.. but you can configure the system where POM is installed to tell you when there are updates?
sorry, yes, I mistook it for the DNS configuration dialogue. the point still stands though - wildcard certificates are not yet implemented, see the referenced bug report.
updated systemd-boot package will hit the repositories shortly on our end, so that upgrading before removing systemd-boot should avoid triggering this issue.
running docker inside LXC is not support in any case. that line removes most of the containment provider by LXC, so it's not a good idea no matter what you run inside the container..
the error messages look like hardware issues, but maybe your system is buggy on the new kernel - those mini PCs very often don't run particularly stable unfortunately.. I'd double check the memory and disks.
a backup should only directly affect the VM being backed up. but of course the additional load caused by the backup can cause issue for other guests as well, if yours system doesn't have enough head room..
found the issue.. this is indeed a bug in systemd-boot's packaging (or rather, a side-effect of what it calls). I'll see how we can avoid this, a reinstall of the kernel package should fix it.
