... oooooor we use systemd which provides things like `systemctl enable foo` ...

i have deployed it to my private servers and my various
laptops/netbooks/etc with great success; quite frankly, it's pretty
awesome, and simple to manage ... should be hitting the main repos any
day now (if not already?) due to recent inclusion of util-linux-2.19.

not exactly OOTB though (yet ... bwa hahahahaha >:-)
