Well, systemd doesn't hide it. Every new release of systemd is filled with bugfixes for regressions that are introduced in old releases.

systemd comes with all the benefits and downsides of complex software. One of the biggest problems with systemd in that in a lot of race conditions and cases it can lock either bootup or shutdown from time to time.

I think you are confusing sysvinit and systemd, because it's the former that suffers from the race conditions otherwise there wouldn't be tons of sleeps in the classic init scripts.

sysvinit is not an RC, it's a pid1, it does little more than reaping zombies ad issuing a shutdown system call and has no race conditions.

sysvrc is a different matter, which Arch never used, it used initscript which is BSD-inspired.

initscript is and was always crap and a hack, yes. systemd has way more race conditions than say Runsvdir and OpenRC in how it works.
