Waiting for the newest Developer Edition, I'm running a relatively recent Solaris Express, B66 (selected the Developer Edition option at boot time). Coming from B57 or so, it's a big boost for laptops. Why is that? NWAM. No, not a new WHAM produced by Maurice Starr, but simply NetWork Auto Magic, an opensolaris project.
Imagine the following. You install B66, networked, with full intent to unconfig the network card and install something like inetmenu, wireless network drivers, write some scripts etc so you can switch between at home wired, at home wireless, at work wired, at work wireless, on the road wired, on the road wireless etc.
Then, you finally login (forgetting to plug in your wired network) and are greeted by a dialog showing you all the various wireless access points and asking you to choose which one you want to connect to. Whoa! This is a cold install and everything was detected, and now this dialog is telling me that I dont need inetmenu and all those scripts to attempt to connect to a network?
iwi0 shows up under ifconfig. I decide to instead go with wired, plug the cable and bge0 is brought up, detects DHCP, gets a new IP and instantly i'm on the wired network.
Pretty cool! Wired or wireless, this pretty much "just works (tm)". Couldn't have been an easier experience.
