Keep ACLs

[Deuscom]

It would be good to reapply permissions from parent target directory.

I suggest to add this (out of adding the respective define in config):

// Remove the TMP_DIR (depends on CLEAN_UP)
if (RESTORE_ACL) {
        $commands['acls'] = sprintf(
                'getfacl %s | sed -e "s/x$/X/" | setfacl -R --set-file=- %s'
                , TARGET_DIR
                , TARGET_DIR
        );
}

just after (in the post section)

// Remove the TMP_DIR (depends on CLEAN_UP)
if (CLEAN_UP) {
        $commands['cleanup'] = sprintf(
                'rm -rf %s'
                , TMP_DIR
        );
}
