As a general rule such things are discouraged, but if the service you're trying to launch already relies on something in /usr[/local] then it's not a problem. For instance, given that setfib(8) is in /usr/sbin then relying on jot(1) (which is in /usr/bin) isn't a show-stopper, although I would have avoided using it on principle, but that's just me. :) Please note, I have no opinion either way on the "setfib in rc.d" idea, and if those who have actual knowledge of the value of the proposal are in favor, I'm not opposed to seeing it committed. hth, Doug > [*] where the root partition that's mounted by the kernel for its root > file system doesn't contain /usr and we mount that via the network > later. > _______________________________________________ > freebsd-rc@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-rc > To unsubscribe, send any mail to "freebsd-rc-unsubscribe@freebsd.org" > -- ... and that's just a little bit of history repeating. -- Propellerheads Improve the effectiveness of your Internet presence with a domain name makeover! http://SupersetSolutions.com/
