From 208877d1e682536aa737748fffe4560956d3908a Mon Sep 17 00:00:00 2001 From: sommerfeld Date: Wed, 13 May 2026 13:43:16 +0100 Subject: feat(etc): template kernel cmdline, derive LUKS UUID from partition name Prompt once at 'chezmoi init' time for the LUKS root partition (e.g. nvme0n1p2) and store it under [data].luksRootPartition in the per-machine chezmoi config. etc/kernel/cmdline.tmpl resolves the UUID at apply time via lsblk, so reinstalls only require re-entering the partition name. The etc deploy script now renders *.tmpl sources through 'chezmoi execute-template' and installs them without the suffix. The resolved UUID is folded into the onchange hash so the script re-runs when the UUID changes even if etc/ content is unchanged. just etc-status/diff transparently handle .tmpl sources (strip suffix for the live-path mapping, render before diffing). etc-re-add skips .tmpl files since template sources can't be reverse-rendered from the live file. --- .chezmoi.toml.tmpl | 6 ++++++ 1 file changed, 6 insertions(+) (limited to '.chezmoi.toml.tmpl') diff --git a/.chezmoi.toml.tmpl b/.chezmoi.toml.tmpl index f41c11a..f7b1156 100644 --- a/.chezmoi.toml.tmpl +++ b/.chezmoi.toml.tmpl @@ -5,3 +5,9 @@ sourceDir = {{ .chezmoi.sourceDir | quote }} [diff] exclude = ["scripts"] + +[data] + # Block device holding the LUKS-encrypted root, without the /dev/ prefix + # (e.g. "nvme0n1p2", "sda2").
