It would be simple with union mounts.

  It would be simple now. It took quite a while to get them right. My first thought was namespaces, but they are even more recent. The ~/.* convention worked a long time ago, far before either union mounts or namespaces were reliable.

    Not that recent considering that's how plan9 works and plan9 is from the 90's. 1992[0] to be exact (apparently). [0]: https://plan9.io/sys/doc/names.html https://plan9.io/sys/doc/names.html

      Even given Plan9, which I was aware of (hey, rc was my shell for a while in the early 90s), how many tries did it take to get right in Linux, even with that knowledge and experience? At least two, arguably three, and, arguably, unless namespaces, we didn’t really get there. (On a somewhat related note, I was very excited that when HP bought Apollo they might integrate the // resource naming into HP-UX. That would have been nice. I say related, because there is a great deal of cool from other systems that died with those systems.)
