3083that the remaining configuration data can subsequently be read if needed for
3084this run of Exim.
3085
3086The configuration file must be owned either by root or exim, and be writeable
3087only by root or uid/gid exim. The values for Exim's uid and gid can be changed
3088in the config file, so the test is done on the compiled in values. A slight
3089anomaly, to be carefully documented.
3090
3091The name of the configuration file is taken from a list that is included in the
3092binary of Exim. It can be altered from the command line, but if that is done,
3093root privilege is immediately withdrawn unless the caller is root or exim.
3094The first file on the list that exists is used.
3095
3096For use on multiple systems that share file systems, first look for a
3097configuration file whose name has the current node name on the end. If that is
3098not found, try the generic name. For really contorted configurations, that run
3099multiple Exims with different uid settings, first try adding the effective uid
3100before the node name. These complications are going to waste resources on most
3101systems. Therefore they are available only when requested by compile-time
