:> I stupidly misspelled 'announcing' in the subject line,
:Well, at least you didn't misspell your name... :-)
:> but it's very real. Check the site out:
:The site looks interesting. All the kernel-level stuff is
:pretty much over my head, but I will be interested in the
:package-level ideas (once work starts on that part).

I have the beginnings of an idea for how to do the packaging
stuff properly... and how to automated it so one gets the
dependancies correct. To realize the idea I will have to get
to the point where a VFS layer can run in userland. Then it
becomes trivial to build 'filtering VFS layers' that run in
userland (i.e. don't take up kernel resources) which can be used
to figure out *exactly* what a package references in the system
and *exactly* what it effects. Once one is able to do that
the dependancy and conflict information can not only be
completely automated, but one can theoretically (and automatically)
create 'environments' for each package to run in which resolve the
conflicts (i.e. makes sure that the exact version of third party
shared libraries and so forth used by a package are the ones that
package sees even if multiple versions would normally install over
I'm guessing 6 months until the project gets to that point, oweing
to the complexity of fixing VFS and, in particular, VFS_LOOKUP.
But then, watch out! Infinite application... not only to the
packaging system, but to the concept of how jails should work as well,
and many other things.
