We may want to have a look at Virtual Square / View-OS, and evaluate in which ways this is related / implemented / implementable / usable / useful in a Hurd environment, and even ;-) strive to collaborate with them. [[I|tschwinge]] found this project very much by chance: on LinkedIn, they posted a proposal for [DevRoom on Virtualization Technologies](http://www.linkedin.com/groupItem?view=&gid=27213&type=member&item=31720076) for [[community/meetings/FOSDEM_2011]]. LinkedIn sends out such posts in very opaque emails from time to time (probably they'd look less opaque with a HTML mail user agent), and I even bothered to have a look at it, and follow the link to the web page, and not delete it straightway. So, I had a quick look at the project: This seems to be an amalgamation / combination of various virtualization mechanisms / projects / ideas. Virtualization is here meant in a broad sense, including file system namespaces: our `chroot` / `settrans --chroot`; networking configurations: our pfinet override stuff; system configuration: subhurds?; current time, devices: likewise?; executable interpreter: our exec server override stuff; "stat" virtualization: fakeroot; etc. -- They seem to do a lot of stuff that we also try to do / could do / can do. In fact, this looks a bit like they're trying to bring some more of the Hurd's [[hurd/concepts]] over to Unix / Linux, more than only the *usual VFS stuff* (translators / FUSE).
