Random question ... does anyone know the history of why is it called
the "emergency holographic shell"?

The earliest commit that I could find on FreshBSD was this one from
Jordan Hubbard, in 1995:

    http://www.freshbsd.org/commit/freebsd/r8828

I also wasn't able to find any reference at all in Diomodis Spinellis'
UNIX history repo:

    https://github.com/dspinellis/unix-history-repo/search?q=holographic

Is it a technical term that I'm not familiar with, or a bit of humor
that has survived?

Or maybe it's an astronomy joke?
