vcs-tag.sh: use more compatible shebang 2025-07-14 13:01:41 +02:00			`#!/usr/bin/env bash`
Make vcs-tag do something useful for non-developer mode as well When building packages of arbitrary commits of systemd-stable, distributors might want to include a git sha of the exact commit they're on. Let's extend vcs-tag a little to make this possible. If we're on a commit matching a tag, don't generate a git sha at all. If we're not on a commit matching a tag, generate a vcs tag as usually. However, if we're not in developer mode, don't append a '^' if the tree is dirty to accomodate package builds applying various patches to the tree which shouldn't be considered as "dirty" edits. 2024-07-19 13:05:11 +02:00			`# SPDX-License-Identifier: LGPL-2.1-or-later`

meson: Use custom_target() instead of vcs_tag() vsc_tag() always reruns even if the vcs-tag option is disabled. Let's use custom_target() instead so that we can only enable build_always_stale if the vcs-tag option is enabled. 2025-04-09 13:54:22 +02:00			`INPUT="$1"`
