7 second boot?
Today, the OpenSolaris "Hello, World" published on Slashdot
had this to say:
...Some other highlights include the GRUB bootloader, SMF (Service Management Facility) which replaces init.d scripts, it starts up processes in parallel for faster boots (7 second boot on a dual opteron workstation I think that was the setup) as well as providing features for automatically restarting...This link generated a massive 4000 hits to my 'blog today, putting me #3 in the blogs.sun.com ranking. I even got an attaboy from MaryMary! While I'm certainly flattered, I felt that these hits were perhaps undeserved-- the claim was so provocative that people just had to click it. We've never made such a claim, though everything else in the sentence is basically correct (see these experts to learn more about new boot and SMF).
So where did that figure of seven seconds come from? Well, we can boot a Solaris Zone in seven seconds-- and by "boot" I mean we go from nothing to having dtlogin up in 7 seconds on a uniprocessor Opteron system (a stock ShuttlePC under my desk). Here is the proof. That said, we do boot pretty quickly on an Opteron system, although you do wind up spending a lot of time waiting around for the BIOS to initialize before the OS ever gets started.
I hope that clears things up. Maybe someday we really will have a seven second boot!
