Used distribution

Linux kernel version used

6.8.2

CPU architectures issue was seen on

x86_64

Component

systemd-repart

Expected behaviour you didn't see

systemd-repart should respect the SOURCE_DATE_EPOCH environment variable when creating files / directories in the local OS tree through xopenat_lock_full with O_CREAT, as it happens here when populating the local temporary tree.

Unexpected behaviour you saw

systemd-repart creates the directories / files in the temporary local OS tree with undeterministic timestamps (i.e. atime and mtime), causing irreproducible image builds.

Steps to reproduce the problem

I've created a repository with a minimal reproduction example here:
