> Ok. But how stable (production ready) the FreeBSD-8-STABLE is? What is your opinion?

I am running 8-STABLE from 27th September on all our ptoduction
machines (from webservers to database servers to the company mail
server) and it is fine. I am going to update again over the next
few days, as there are some ZFS fixes in which I want - and which
may benifit you too - so I will be able to report back next
week as to how a more recent version behaves.

In general though, I have never had problems running STABLE on
prodyction systems over the years. Of course what I do is to test it
on a singlre machine before rolling it out (a leaf in a webfarm
so if it goes down it wont affect the business) but it is usually
fine. keep an eye on -STABLE mailing list though, as that is where
problems arise. I watch that, and also the dailing commits, either here

http://www.freshbsd.org/?branch=RELENG_8&project=freebsd&committer=&module=&q=

or here

http://www.secnetix.de/olli/FreeBSD/svnews/?p=stable/8

Just to see whats going into the tree relative to whats being discussed.
It only takes a few minutes a dat to monitor the mailin lists and the
commits, and the result is that we've been running STABLE for a very
long time (close to a decade I suspect) with great success.

-pete.
