Notes for neovim - reproducible builds result

Version annotated: 0.1.5-2
Identified issues:
Identifier: captures_build_path
Description Captures build path, e.g., /build/1st/foo-42.0 v. /build/foo-42.0/2nd
.
Until early 2024 we varied the build path when testing packages from unstable
and experimental, which we have stopped doing now as the build path is recorded
as part of the environment and thus can be used when rebuilding.
.
This issue is kept here for the time being.
.
This issue is only for miscellaneous issues which need individual fixes,
please create new issues for specific issues, e.g. gcc_captures_build_path.
.
Here follows some general tips for packages using the standard GNU toolchain:
.
If using autoconf, make sure you call ./configure via a relative and not absolute path.
.
If your issue is related to using the `__FILE__` macro, or the recording of
--debug-prefix-map flags in non-GCC non-debugging output, this is what is
fixed by our patch mentioned above; you should not need to fix it
specifically in your package.
.

Comments: Two differences:
1) Captures hostname (near the start of .rodata).
2) .rodata of /usr/bin/nvim includes "hostname\0" (literally those 9 bytes) in first build but not in second build.
.
These two may have a single cause: in the second build the hostname is "i-capture-the-hostname", so the compiler may have combined string literals, i.e., used the end of the string literal "i-capture-the-hostname" as the literal "hostname".
.
Also captures username.
