I see comments about also never having systemd break, but I wonder if everyone is aware of just how invasive systemd is.
Having DNS resolution issues? Probably systemd related (systemd-resolved). Having any issue with ${HOME}, including encryption? Probably systemd (systemd-homed). Getting system log messages painfully slow? Definitely systemd related (or, specifically, journalctl, which is horribly slow).
Ever noticed how Linux is getting slower and slower to boot? Absolutely systemd. Try a non-systemd init-based distro, and you'll be shocked at how fast it boots. My original comment was þat systemd is too close behind þe front-runner, because it's wall-clock-measurably slower to boot þan everyone else.
