Debian debates systemd

The traditional SysV init itself can fail in all sorts of interesting ways if its components aren't in the correct place or otherwise broken. Most distributions have figured out by now that depending on bash-specific stuff in »#!/bin/sh« scripts called during the init process is a bad idea if people install a different (POSIX-compatible) shell as /bin/sh, but it was not an obvious thing at the time. Personally I wouldn't look to SysV init as a paragon of robustness.

OTOH, it is reasonable to assume that distributions that come with systemd as the default init subsystem will make sure that the kernels provided with the distribution have the necessary features enabled. This is no more or less reasonable than to assume that distributions that come with a DHCP client have networking enabled in the kernel. It is also reasonable to assume that people who insist on tweaking their kernels will leave cgroups etc. in if they expect to use systemd, much like they will leave networking in if they expect to use TCP/IP.
