Which Style Init Scripts Do You Prefer?
An anonymous reader asks: "I started using Linux years ago, with a Red Hat distribution. When Red Hat's custom configurations started getting in my way, I jumped ship to Slackware. I have never looked back except that I cannot stand the BSD style init scripts. I like having a full compliment of run-levels and control on the fly over which scripts will be running, and which ones will not. That is hard to achieve, when you put multiple configurations in the same file. I also liked having the scripts around to start, stop, and restart services. While I was rewriting my own startup scripts [based on Debian's scripts], I discovered that there is a third style, based on dependencies. AFAIK this is the style adopted by Gentoo. I don't want to start a distro war; but, I am curious about what kind of init scripts Slashdot readers prefer, and what they think are the benefits of each."
You might want to take a gander at FreeBSD 5's RCng (also available in NetBSD, and possibly OpenBSD).
/etc/rc.d. Want to restart your sshd? /etc/rc.d/sshd restart. Very similar to init.d.
It combines, in my opinion, the best of both worlds:
1. Full control over each service through scripts in
2. Dependency-graphs determine service start order. Each file contains a special header declaring its dependencies and what it provides; the system analyzes these on boot, or when you request that a specific service be started, and handles the dependencies for you.
Mmm, tasty.
(And yes, this is quite similar to Gentoo's system, except that Gentoo translates the scripts into actual runlevels behind the scenes, whereas the BSDs do not. That, and this doesn't use python.)
