I remember back a while when 5.x had been recently released
as STABLE and the conventional wisdom said not to use it in
production until the 5.3 release.
Is there any such conventional wisdom as regards 6.x?
my home system is actually production system that can't be stopped for a
long time. i moved finally from NetBSD for various reasons including real
SMP support (real=not crashing and not all-giant lock).
what i can say is
1) performance is excellent. maybe it should be named FastBSD not FreeBSD :)
2) it DO has bugs, but i already filtered those than can make a problems
for me.
3) first bug - kldunload means danger. many kernel modules just crash the
system when unloaded. solution: just don't do it, not a real problem.
4) using kernel-ppp+pppd=crash after not a long time. that forced my to
learn user ppp(8) which is actually MUCH better. same solution as 3.
anyway i don't see any reason why kernel ppp is maintained at all. user
ppp+tun interface works perfect.
5) sio driver has bugs. no crashes but overruns are reported by thousands
unless i patched sio.c to increase buffer eightfold. the real bug is
somewhere else, and can always be repeated with just
dd if=/dev/ad0 bs=1m of=/dev/null
the larger bs - the larger buffer have to be set to fix it until some
value than enlarging bs to anything doesn't break things at all.
i don't know how this all works in kernel so have no idea about the real
fix.
but this fix is enough for now. if you don't use high-speed serial it
shouldn't be a problem for you anyway.
6) still have to learn ipfw more, an excellent tool! incomparably better
than NetBSD's ipf!
found no bugs on other things and system works stable. for 4 days now but
stable without any problems, having stable 921kbps ppp link (which is my
outbound connection) and all userlevel programs working fine.
