Upgrading OpenSolaris with a few clicks

One of the
significant enhancements of OpenSolaris 2008.11 is the IPS, image package
system. Several critical bugs have been fixed. IPS now becomes a good friend of us to
manage the system. E.g., I’m using the May release of OpenSolaris. After updating
the SUNWipkg to the latest version(0.5.11-0.101), I upgraded the entire OS to
2008.11, easily. The process went smoothly either on bare metal or VirtualBox.
One of the virtues of IPS is, it creates a new boot environment for the November
release automatically. You can boot back to you old May release any time if you
want.


Here are the
simple steps about how to upgrade from 2008.05. You can also find the
procedure on OpenSolaris.org
.


$ pfexec pkg refresh
$ pfexec pkg install entire@0.5.11-0.86
$ pfexec pkg install SUNWipkg@0.5.11-0.86
$ pfexec pkg install SUNWinstall-libs
$ pfexec pkg image-update


That's it. After 2008.11,
the process gets even easier that we can use the GUI based package manager to do the OS upgrading.  Here's a demo.


BTW,
VirtualBox 2.1 is just released. I feel it’s faster than v2.0.2. This is really
a good news, even better than the new features.
