Thinking out loud...

Hey Folks,

While I'm waiting for my new machine to arrive (vmware is just too painful on my work machine) I got to thinking about Dragonfly. I figured I'd just put them out here for comment so...

1) I'd like to see something like OSDL's push for "data center" grade Dragonfly (see http://www.osdl.org/lab_activities/data_center_linux/ for what OSDL is pushing for Linux).

While I'm not sure how much is relavent work could be started on getting NUMA support for Dragonfly. We could solicit vendors for NUMA hardware and the like. I'm willing to start up that campagin.

Hotplug PCI/CPU support. There is a lot of heavy duty hardware that has this option. I don't think any of the BSDs have hot-plug support. Again I'd look for hardware to work on.

I'd also like to see something like "domain" isolation for CPU and memory (think Solaris). I have no idea where to start with this.

2) While Matt and others work on the VFS replacement we should probably come up with something in addtion to SGI XFS as a file system option. W It would be good if we had some answer to Microsoft's WinFS (some sort of "database-like" thing).

I recently saw on Windows 2003 to use SQL like statements to query different parts of the system. BeOS I believe had something similar for BFS IIRC.

3) I'd like to see a binary update service. For FreeBSD there exists freebsd-update (http://www.daemonology.net/freebsd-update/) and that would be a good starting point. In the long run maybe something like an automated update service for those who don't want to deal with patching source. (I totally agree that patching the source is just too easy and just plain convienent - That should be an option. I think that there are some sites that don't want to do that for one reason or another and would prefer to have a binary update "service".)

4) I know that Robert Watson put up a LXR service (http://fxr.watson.org/fxr/source/?v=DFBSD). What about setting up a Bugzilla server as well?

. ..

I realized while typing this up; A lot of this probably sounds like "well {Linux, Sun, whoever} is doing this so we should to." I think that there might be a little bit of it in there and all of this just maybe outside of the scope of what Matt has in mind for Dragonfly.

Anyway, like I said I'm just putting this out there for comments.
