Tru64 featured AdvFS, which was awesome for the time (pre-ZFS).<p><a href="https://en.wikipedia.org/wiki/AdvFS" rel="nofollow">https://en.wikipedia.org/wiki/AdvFS</a>

Surprisingly Tru64 only reached end-of-life in December of 2012, with the last release happening in 2010. Depressingly, some of the modern software I write at work is required to be compatible with Tru64 5.0 as some of our customers are still running that OS.
This link isn't for a post on Tru64 but rather:<p>"Unix OS archaeology – Soviet UNIX clone DEMOS pt.2"<p>Also interesting but perhaps correct the URL in the title?
