Indeed. But all of those items can be omitted from the config if you don't want them. Predefined macros would not be optional. > Correct me if I am wrong, but I am under the impressions that a 'hostlist' is > handled much as the described parsing for a MACRO, i.e. - end-to-end > expansion & > substitution, called on or not...

That is, only when it is about to be used. > - while a 'lookup' - be it file, db, or SQL - is ignored until actually > encountered in acl that *uses* it, IOW, skipped in many cases.
