Do enlighten me - where can I read up on this (shmem on dragonflybsd being slower than SysVshm)?

SSI would be when multiple connected computer running an instance of, say, dragonfly bsd, can act like a single (multi-user and multi-tasking) computer. Tasks will migrate to any processor core in the cluster (and ideally factor in the cost of migration over network).

Similar to what openmosix did for linux ages ago - and very different from the infamous beowulf cluster.

By the way - Hammer does not only do simple snapshots but it does them automatically in intervals. So if you use it with samba or nfs you get sort of an instant apple time-machine workalike - albeit with deduplication and all. Only disappointment for me was that trying it in a VM was not really going well - you need a spare PC for that.

Yeah, OSnews has mostly become a mobile website, but I still enjoy it more than Slashdot nowadays.

while many features of ZFS (and Hammer) are included in btrfs too, Hammer (specifically Hammer 2) has design goals that go way beyond those of ZFS (I believe it is going to be a fully fledged cluster FS). So there is something to wait for.

And I am still hoping that theiy will pursue their single-system-image design goal eventually.

I installed a Solaris 10 prerelease on my inspiron 8200 notebook, which is definitely not sun approved, and it (now) works perfectly fine, even with my nvidia graphics card.

I did, although, notice the exact same problems as the original poster (like "eject cd" not doing anything etc.), and it took me quite some tweaking to get X going and to configure a german keyboard. The keyboard config thing is definitely an installers job and differs a lot from linux.

There are some rough edges there (never mess up your X config with xdm login on until you know how to boot into single user mode), and some things are beautiful and quite configureable, like ksh, but not preconfigured worth a dime when they come out of the box!
