Sorry, but as it's been said in this list, there are several use patterns for FreeBSD. I use it in both a laptop and a PC and I boot them every time I want to use them. Believe it or not I don't like let them consuming energy and making noise during night, specially the laptop :) So please, let's assume FreeBSD has to be (re)booted from time to time and not only for OS upgrades or when it crashes. Also, in embedded systems, boot time is an important factor. > > -- > Atte Peltom=E4ki > =A0 =A0 atte.peltomaki@iki.fi <> http://kameli.org > "Your effort to remain what you are is what limits you" > _______________________________________________ > freebsd-hackers@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-hackers > To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org= "
