OpenSolaris 2008.11 snv_91 X86

I updated to build 91 of OpenSolaris from build 86 (which is what we shipped in May). The download and install seemed to go reasonably well. I don't think I broke anything, but I had a few questions. Instructions to update in this thread right here [indiana-discuss] Repository update: snv91.
Comments:

Every time you do an image update, OpenSolaris, via Sun's super duper "ZFS" filesystem, will, before you are aware of it, create a new "snapshot" for the newly updated system, and very smartly make it your new default boot system.

But more importantly, OpenSolaris will also save your old system as another snapshot, and allow you to select and boot back to your old system in case anything goes wrong in the update.

In today's complicated computer system, this is the best system I have ever seen.

But OpenSolaris does much much more than that. You can constantly create snapshots with very little overhead or penalty. Even if you are too lazy to create snapshots (or should I say, when I am too lazy to . . .), and godforbids you screw up your system, you can ALWAYS go back to exactly the state when your system was first created (no need to re-install from CD/DVD). This is almost like an insurance policy (life or health), eventually we will all realize that no one can afford not to have one.

But, again, OpenSolaris does much much more than that. :-)

hey ... thanks for those thoughts. Hopefully I won't need the backup, but if so I'm glad it's there. :)

There's no doubt about it, zfs + ips for to upgrade the system have been a great idea, one that shows the potentiality and advantages of opensolaris over other OSs, but I think that ips need some improvements: for USA and europeans users is not problem, but for us where the internet connections are at 768/512 kbps is a disappointment to see the following message:

After four hours of downloading time (each attempt), just to see that the upgrade failed at the final stage.

We'll be glad to see the PKG xxxx RESUME feature.

Though I like the direction of IPS and OpenSolaris 2008.05, today I was doing my upgrade from b86 to b91 which didn't go so well. After download about 2.4 Gb for the upgrade, only after some time during the install phase did it fail due to insufficient disk space. Sure would have been nice if IPS checked the free disk space prior to the long download.
