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 14:05:11 +03:00			`#!/bin/bash`
