BTW you can control systemd and how fast it chooses SIGKILL after sending SIGTERM. I don’t know why people complain so much about it. It’s really just there such that things on your computer end properly without any sort of data corruption or something bad going on after a reboot or the next time you turn on your computer.
I didn’t even know this happened. Mainly because the moment Google blocked rooted and custom ROMs for Google Messages. I just stopped using the app outright.
