Jehanne: Plan 9 with a POSIX layer
 

This is not entirely un-interesting: Jehanne's sole developer took Plan 9 and added a couple of convenience improvements, like a library to support POSIX. As a proof of concept, the mksh was ported to it. I heard rumors that NetSurf could be ported as well - that would make Jehanne the first "Plan-9-like" operating system with a decent web browser. :)

I'll definitely keep an eye on it.

I've run plan 9 already, kind of a interesting OS. I'd be interested in trying this one.

Let us know when they release an iso. AFAIKS it's still just source code.

The interesting part is, I discovered this project earlier today, via your plan 9 text editor links in a previous post.

It seems plan9(base) is getting a little more attention recently. I think another project is called HarveyOS(just source so far). But so far the only iso's I could find were plan9(old) and 9front.

Harvey OS is one of the projects used for Jehanne, according to the README. :)

I tried to use Plan 9 once, but I couldn't get my brain around it, if they can make it more intuitive, I may try it again. ;)

I'm curious what part of plan9 you couldn't "get".

My biggest hurdle was figuring out the WM(rio). It is also hard to figure out what is installed. Luckily I'm decent on a terminal.

rio's documentation is OK, I'd say. Rob Pike usually talks a lot about what he did, waiting for someone to pat him on the back. :D

In case you were wondering.

Now I'm wondering if you built that from source. Reading the docs make it look like it might be fairly easy. Any tips?

Yes, I did.

Wait for ISOs. :D

Building and running it on your existing operating system is fairly easy though - the Jehanne toolchain is quite usable and its documentation is good enough. Remember that this project lacks manpower yet, so while it has a couple of nice additions when compared to the Bell Labs distribution, there will be rough edges. Also, if you're already using deadpixi's sam editor, you'll probably wonder about missing features - the Lucent Public License is not really compatible with the GPL.
