Subject: [PATCH core] gnu: patchelf: Build from git sources.
Date: Sat, 28 Sep 2024 14:12:03 +0200

From: Attila Lendvai <attila <at> lendvai.name>

Rationale: it makes it much easier to build a pending PR by using
`(commit "pull/544/head")` in the origin, or in general to experiment
with different patchelf versions.  It also makes it more resilient
against attacks hidden in release tarballs.

sadly, this leads to endless rebuilds...

i think should "(git-file-name name version)" ?

Just a question, why do you need to change to bootstrap here?

It would be nice to mention removing labels and adding new dependencies
in the submission, and etc/committer.scm maybe useful.

hrm. i tried that at first, but it errored out with `name` being undefined. i retried it just now to double check, and now it works. i must have been confused by something.

the updated patch will have `name` in there.

because the last substitute* touches `tests/Makefile.in` which is generated by the bootstrap phase (by the auto* tools).

but now that you asked, i've changed it to target `tests/Makefile.am` instead.

ok, i'll send an updated patch soon.

BTW, etc/committer.scm broke on this package. i've sent a patch to fix that:
