The Ethos Operating System

I&#x27;m confused. Two things.<p>1. My initial impressions is that the idea is to build an OS that breaks from the past, but then later there is a promise to port to POSIX. Doesn&#x27;t that restrict some of the design decisions that could be made when starting with a clean slate?<p>2. What does this offer over unikernel-based operating systems such as MirageOS, HalVM, LING, OSv, etc...? Basically seems like they already do what Ethos plans to do.<p><a href="http:&#x2F;&#x2F;wiki.xenproject.org&#x2F;wiki&#x2F;Unikernels" rel="nofollow">http:&#x2F;&#x2F;wiki.xenproject.org&#x2F;wiki&#x2F;Unikernels</a>

This would be so much more interesting if it was actually available for download. It&#x27;s sad that djb&#x27;s minimallt seems to be stuck with ethos non-release. I remember them promising open source release &#x27;soon&#x27; back in 2013 when it was initially published, but there doesn&#x27;t seem to have been any progress in that direction.<p>Has anyone poked the authors recently to hear what&#x27;s going on?

&gt; Most of our programming is done in C (kernel) or Go (user space). [1]<p>It&#x27;s cool that Go is being used in a project like this. For some reason I found that a bit surprising.<p>[1] <a href="http:&#x2F;&#x2F;www.ethos-os.org&#x2F;background.html" rel="nofollow">http:&#x2F;&#x2F;www.ethos-os.org&#x2F;background.html</a>
