I've investigated the possible solutions to avoid including the paths into the
binaries.
I've found this:
https://github.com/golang/go/issues/16860
It's still unresolved and only planned for Go 1.13.
In the meantime, I've played with the -trimpath option to see if I could get
something out of it.
I've added this to Go's (build) function:
--8<---------------cut here---------------start------------->8---
"-asmflags=all=-trimpath=/gnu/store"
"-gcflags=all=-trimpath=/gnu/store"
--8<---------------cut here---------------end--------------->8---
The resulting binary is indeed trimmed, but that's not enough: it seems that
Guix detects the remaining part of the path as a store item and includes it in
the list of requisites. Is this really how Guix works? It does not need the
full path?
Go supports only one call to -trimpath, so we can't even set this to the Go
inputs.
Regarding Boyer-Moore over the binary, we would have to apply the changes for
all recursive Go libraries. Now is there a reliable way to detect what's a Go
library and what is not? We don't want to patch non-Go libraries, right?
(Let's not forget that there is CGo...)
If we can't think of a way to detect a Go library, Boyer-Moore does not seem to
be a solution either. And we might have to wait for Go 1.13...
