Subject: [PATCH v2 01/16] refactor bootstrap: store rootfs tar with user permissions
Date: Fri, 27 Feb 2026 15:57:01 +0100	[thread overview]
Message-ID: <20260227145716.3794146-2-felix.moessbauer@siemens.com> (raw)
In-Reply-To: <20260227145716.3794146-1-felix.moessbauer@siemens.com>

As the mmdebstrap itself is executed as root, the generated rootfs will
also be owned by root when stored as file. To avoid this, we let
mmdebstrap emit the rootfs on stdout and write it to a file outside of
the sudo call.
