The most obvious ones (IMHO) are: > - Lack of dependency handling for manual start/stop which is not really a problem and often an adventage. > - No provision to automatically restart a daemon if it dies. but it should not be a part of rc subsystem at all. First - deamons should not die without reason. If they do, admin should clearly know it and feel it's effects, and after fixing a source problem , restart it manually. in case when you are for some reason required (temporarily of course) to use daemons that often dies, then just make restart wrapper shell script and put it in place of actual daemon in rc.d script. This is what i do with asterisk process that rarely but do crash. But i did it myself and any responsible admin should do this himself, knowing a problem. The proposition sounds for me somehow like windows XP/7 solution that restarts services and windows explorer so it "doesn't fail". Such ideas and methods of constructing operating environment is possibly acceptable under linux community, MAYBE for PC-BSD, but not for anything serious. there is IMHO already too much automata in default FreeBSD: default /etc/crontab, /etc/newsyslog.conf and /etc/periodic directory. All gets deleted by me as soon as i install FreeBSD. All of this mechanisms are good, but none should be in default system install with possible exception: */5 * * * * root /usr/libexec/atrun */11 * * * * operator /usr/libexec/save-entropy Everything else should be run after clear request and knowledge of sysadmin. scripts from /etc/periodic should go to /usr/share/examples
