From f405a2ceda90c8b6ade2d597d3ebea761c03ad35 Mon Sep 17 00:00:00 2001 From: Erik Arvstedt Date: Sat, 22 Oct 2022 19:37:49 +0200 Subject: [PATCH] make-container.sh: improve root handling Don't auto-switch to root when executing make-container.sh, because auto root switching is also implemented in extra-container. Besides simplifying the code, this is useful for a later commit that introduces flakes-based container building. With this change, the container is built under the regular user instead of root, thereby utilizing the user's regular fetcher and evaluation caches. --- test/lib/make-container.sh | 17 +++++++---------- 1 file changed, 7 insertions(+), 10 deletions(-) diff --git a/test/lib/make-container.sh b/test/lib/make-container.sh index 19d009f..491cddf 100755 --- a/test/lib/make-container.sh +++ b/test/lib/make-container.sh @@ -53,16 +53,6 @@ set -euo pipefail -if [[ $EUID != 0 ]]; then - # NixOS containers require root permissions. - # By using sudo here and not at the user's call-site extra-container can detect if it is running - # inside an existing shell session (by checking an internal environment variable). - # - # shellcheck disable=SC2154 - exec sudo scenario="$scenario" scriptDir="$scriptDir" NIX_PATH="$NIX_PATH" PATH="$PATH" \ - scenarioOverridesFile="${scenarioOverridesFile:-}" "$scriptDir/lib/make-container.sh" "$@" -fi - export containerName=nb-test containerCommand=shell @@ -80,9 +70,16 @@ done containerBin=$(type -P extra-container) || true if [[ !
