"Journalctl is systemd’s much-maligned replacement for syslogs. Crusty old nerds like me are mad it’s not just a text file. But the binary format actually has a lot of advantages, you can efficiently do simple time and metadata queries. I also like the color pager it gives you. Now that I’ve learned a bit about the journalctl tool I like it more."
I feel like this is probably more common a story than people admit to, or will let themselves get into.
