What is the meaning of this . I mean sync. all source and start to build new system from the beginning is to hard , it takes too much time and can have some risk .I don't understand How ISP can use FreeBSD because at the building time , machine will be off. Okey Maybe yahoo can use it because it's clustered environment and it's easyly remove one of the machine install new version or patch it if any problem occur it can be reinstalled after that making standart configuration now it's ready. I think that Kernel must be seperate of userland because it's managing and controling processes and I don't need rebuild kernel too much if I have no problem with device driver or if I don't need to add something to kernel for support ( instead of Firewall or like important things ) . Why some programs are in base system . What is the meaning of Sendmail or SSH in base system . Programs are only executable things What is the relation about those programs with base system ?! in list Some members said that I can patch a system with watching Security Advisories but same people said that " Sometimes it'wont and I have to do full kernel / world / build / plus install and reboot " Why ? What is the problem ?! Which list I have to watch for which Relese will have production quality ?!!
