This project has a release tarball (which are distinct from
autogenerated tarballs and won't suddenly change):
https://github.com/storaged-project/libbytesize/releases

Can you change to use that instead?

Please move these parenthesis up to please 'guix lint'.

Nit-pick: margin comments are typically not capitalized and has no
spacing between the ; and the text.

Note that since the previous 'core-updates' merge, the equivalent of
this should now be invoked automatically if needed.  Can you try
removing it?  If that doesn't work, use (replace 'bootstrap ...) here
for clarity.

The rest LGTM.

> +@item How to store the given size so that no significant information is lost?
> +@item If we store the size in bytes, what if the given size gets over the
> +MAXUINT64 value?
> +@item How to interpret sizes entered by users according to their locale and
> +typing conventions?
> +@item How to deal with the decimal/binary units (MB versus MiB) ambiguity?
> +@end itemize
> +
> +@code{libbytesize} offers a generally usable solution that could be used by

> +language with thin bindings for other languages.")
