When guix is configured with an alternate "prefix", why isn't "store-dir"
relative to this alternate prefix? Yes, it is possible to specify something
like, "--with-store-dir=<some-prefix>/gnu", but some people expect all
files/directories to be relative to "--prefix" to isolate source based
installed software from their base system.

Because, it enables Guix to download and use pre-built binaries
(substitutes).  This is a feature many wound want to have as compiling a
package can take a lot of time (especially when doing it for the first
time).  These binaries are built with their prefix directory set into
'/gnu/store/...' and they will be valid only if they are installed into
'/gnu/store/...' on your system.

The `--prefix' option will still let you install Guix into a directory
of your choice and still be able to download substitutes along as you
didn't configure with a different `--with-store-dir'.
