I run Solaris 10 at home here and it's just ok I think. Like Thor says
they reworked the /etc/init.d start up procedure (like I still can't find
where they start sshd at boot) and the gcc you get from sunfreeware takes
a little toying with to get working. It tries to use solaris 9 headers so
you bascially have to rebuild them.
It seems solid though... it boots alot faster. I haven't used any of the
admin tools (although to be honest I never used any of the Sun admin tools
that were intended to manage hundreds of servers at the same time).
I haven't seen it in a production app although I've heard there are alot
of realtime java hooks in the file system to make an atempt to make java
perform better.
ZFS is just like Tru64's advfs or hpux's file system that gets installed
by default. It's a smart filesystem that Sun has really been behind the
curve on and it's about time they did something about it. Like I said,
DEC had been doing this for years and HPUX installs a smart fs when by
default that lets you grow the filesystem. It's shrinking the filesystem
that all these things don't do too well.
Althogh I haven't used ZFS is it's anything like advfs it's got a little
gui that lets you "draw" out the filesystem across your disk array.
Whether or not you surrive a disk failure depends on how you have your
raid set up. So you probabaly use it in conjunction with Soltice
Disksuite.
So in the end it's alot like Vertias' vxfs filesystem with a few tweaks.
Sun figured out that people buy their products and then install vxfs and
the Veritas Volume manager. Sun figured out that they were losing that
business. Sun would love to put Veritas out of business... not only for
the filesystem but with the clustering software too.

To anyone working with Solaris 10, how do you like it? Have you tried
out any of their fancy new tools, are you excited about ZFS whenever
that comes out?
I have it on a spare server, and have installed some monitoring stuff on
it to play around with. First difference i noticed was trying to turn off
services and i couldnt find any startup scripts in the /etc/rc
directories. There are admin tools called svcs and svcadm for monitoring
and controlling your services.
It all comes under the banner of the predictive self healing,
and is somewhat like the djbernstein daemontools package for monitoring
other daemons.

Mr. McKittrick, after very careful consideration, sir, I've come to the conclusion that your new defense system sucks.
