[systemd-devel] /etc/initscript equivalent for systemd?

[ccox at endlessnow.com]

In sysvinit, at least on SLES and RHEL, you could use /etc/initscript as a
mechansim to get "shell" control things like ulimits to take hold system
wide, since /etc/initscript was invoked as a wrapper around all init
scripts.

So.. where do we set system wide ulimits at in systemd?  Sounds like it
has gotten more complicated (??).

Forgive me if this is a FAQ-like question... I didn't seen anything using
Google to search the archives.
