Every stable system starts with a rock-solid hardware. Without proper hardware,
it won't matter what OS you install on it. I had a slew of issues with 4.x on flaky
hardware. I have had pretty loaded servers running 7-8x for years at a time
without reboot. I did run into few bugs with 4,6,7 releases, had to submit a bug
and to get it fixed. I also ran into a problem upgrading from 7 to 8 on one of my
machines with MBR out of whack somehow. I don't believe that got fixed. So
I will have to do a clean reinstall of 8 to upgrade. I must say, FreeBSD is VERY
sensitive about flaky hardware. It is a lot less forgiving, thus the more panics. It
is both good and bad. On one hand you will know that your hardware is bad
and or failing, on the other you will get panics and downtime.
I agree with you on performance tuning. It could come with pretuned settings
out of the box. The fact that you have to tune it is in its roots. I believe it's
very hard to have a one fit-all settings. It is fairly simple to tune it. This isn't a
point-click OS, after all.
I also agree that the need for storage is expanding very rapidly. All the media
and cloud computing pushing storage to its limits. I am also in need of a stable
yet affordable NAS solution. I tried UFS2 with NFS several years ago without
great luck, so I gave up. I'll look into ZFS soon. I've had entire RAID5 fail on
more than one occasion, so I know something like ZFS is important to have.
My 2 cents.
