fd_copy_directory() iterates the source directory with FOREACH_DIRENT_ALL, i.e. plain readdir(). For ext4 sources (and similar) that order depends on the directory hash and varies between hosts, which leaks into destinations that record entries in insertion order. systemd-repart's partition_populate_directory() stages CopyFiles= into a temp directory and then later builds a filesystem from it; with the unsorted walk the staging order ended up baked into the output (most visibly when the destination is vfat, where dir entries are stored in insertion order). Replace the raw readdir loop with readdir_all(RECURSE_DIR_SORT), which collects and qsort()s the entries by name. Dot/dot-dot are filtered by readdir_all() so the explicit dot_or_dot_dot() guard is dropped. Co-developed-by: Claude Opus 4.7 <noreply@anthropic.com> Signed-off-by: Paul Meyer <katexochen0@gmail.com>
