@vorlon systemd-logind and systemd-nspawn did modprobe in ExecStartPre= and the new service is a nicer way of expressing the needed modules.
https://github.com/systemd/systemd/commit/625077264ba01a108386eeea733ee244e6b7ff14 The tracing files will still be present at the old location for backward compatibility and the new location is the desired location according to the kernel documentation: https://www.kernel.org/doc/Documentation/trace/ftrace.txt ... When tracefs is configured into the kernel (which selecting any ftrace option will do) the directory /sys/kernel/tracing will be created. To mount this directory, you can add to your /etc/fstab file: tracefs /sys/kernel/tracing tracefs defaults 0 0 Or you can mount it at run time with: mount -t tracefs nodev /sys/kernel/tracing For quicker access to that directory you may want to make a soft link to it: ln -s /sys/kernel/tracing /tracing *** NOTICE *** Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing All files located in the tracefs file system will be located in that debugfs file system directory as well. *** NOTICE *** ... The .mount will fail in LXC until the fix for LXD lands and it bind-mounts it. I can set ConditionVirtualization=!lxc until all supported LXD versions do that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867972 Title: [FFe] Please accept systemd 245.2-1ubuntu1 to Focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1867972/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
