But the users would be helpless even if they saw the deprecation messages!

Developers, on the other hand, are the target of such messages. I cannot imagine developing a low-level component – like systemd – and not running `dmesg` from time to time. If you use kernel features more than anyone else, you should pay more attention than anyone else.

So first of all "dmesg" doesn't work anymore on Fedora (you need perms now).

But even beyond that: there's *so* *much* *stuff* in dmesg right now. It's a wall, a deluge of text. Don't expect me to read all that. I only look there when I am looking for something, and then I usually do "journalctl -ke", and it never showed up there.

Fedora just flipped the default, starting with their 6.8 kernels IIRC.

Reverting it is just a matter of:

sysctl kernel.dmesg_restrict=0

Fortunately, it's rare when anything beyond the final dozen or so lines matters. (eg the messages that show up when you plug something in, or if something goes wrong...)
