I always hated the prevalence of so many tools -- I get sick of having to learn 30 variants of the same stupid thing because none of them seem to excel in every area. One server from recent memory had crap running in sysv, inittab, and with deamontools because not everybody liked the same system and kinda just did what they knew. I'm rather happy that systemd throws all that out.
That's just lousy technical culture. If you can't ensure you've got clean practices on your servers to that degree, you've got bigger problems on your plate.
