There's no need to do a wholesale replacement of the RC system in FreeBSD to support this concept. What you are describing are "service profiles". And we already have a single file that describes the default "service profile" for FreeBSD: /etc/rc.conf. That lists every service that should be started (or stopped). All that's missing is a way to tell the RC system to use a different rc.conf file (like rc.conf.mobile, or rc.conf.wireless or rc.conf.whatever), and to run through the RC setup based on that file. Our current RC system does everything needed except: - parallel execution of items that don't depend on each other - monitor running services and restart them if they crash Compared to all the init/RC systems on Linux, ours has *many* advantages, not the least of which are: - very simple text configuration file - only 2 directories of init scripts to worry about (/etc/rc.d; /usr/local/etc/rc.d) - ability to create "generic" or global config file (/etc/rc.conf) with local overrides (/etc/rc.conf.local) - ability to see the exact order that things will start (or stop) via rcorder - everything is written in nice, simple, sh We don't need to replace a perfectly working system. Maybe it needs improving, but it doesn't need replacing. -- Freddie Cash fjwc...@gmail.com _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
