Solaris and OS X

And then there are all the cool Solaris goodies to take advantage of. I'm totally addicted to Zones and ZFS. For example: I have my laptop set up with ZFS managing the disk. Then I mirror the laptop's disk onto a USB drive. When I'm wandering around with my laptop disconnected, the filesystem runs in "degraded" mode - which simply means that the mirror isn't up to date - it's as fast as ever. But when I get back to my desk and the USB drive reconnects, ZFS magically updates the mirror and I have an incredibly fast backup. If I want to use backups for going back in time, ZFS snapshots are perfect and fast.
There is one area that's a problem: when I close the lid on my laptop, it keeps right on running. It doesn't suspend. I have to manually shut the system down. I've been bugging the Solaris folks about it for a while: they're working on getting there, but it'll take awhile. In typical Solaris fashion, they're going for a "solve world hunger" scale solution: last week I was at a talk about Tesla, the upcoming power management system. It'll be great when they're done.
And no, I don't use any of the virtualization/multiboot facilities: They all consume more performance and disk space than I'm comfortable with.
