From d5f8b50365533f2713596f59519c48019f6b1f19 Mon Sep 17 00:00:00 2001 From: Maxim Cournoyer Date: Fri, 3 Mar 2023 21:09:33 -0500 Subject: pack: Move common build code to (guix build pack). MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The rationale is to reduce the number of derivations built per pack to ideally one, to minimize storage requirements. The number of derivations had gone up with 68380db4 ("pack: Extract populate-profile-root from self-contained-tarball/builder.") as a side effect to improving code reuse. * guix/scripts/pack.scm (guix): Add commentary comment. (populate-profile-root, self-contained-tarball/builder): Extract to... * guix/build/pack.scm (populate-profile-root): ... this, and... (build-self-contained-tarball): ... that, adjusting for use on the build side. (assert-utf8-locale): New procedure. (self-contained-tarball, debian-archive, rpm-archive): Adjust accordingly.
