(i mean no crashes etc...) i will get real IPv6 zone allocation soon and want to use it. 5) what is used in FreeBSD for traffic management. NetBSD has altq - please just give me a name i will RTFM. 6) how to turn using serial port as console on i386? my home machine is headless, i'm using X terminals to access it. 7) does FreeBSD support 2 CPUs on i386? sorry if too much questions at once, i would like to move my home machine to FreeBSD tomorrow, test it at real for a month and then (if it will be better than NetBSD for my needs) replace other machines. should i go to 4.10 or better 5.2.1? stability is really important to me.
