This was fixed about 8 months ago - if you have a recent copy of the source, a trailing comment is harmless in the inputs and bundlesequence. However, other than that, your syntax is otherwise about 70% wrong :-/ It should be: body common control { #. Core - Minimal (Don't EVER break these!)... bundlesequece => { "Client", "Server" }; inputs => { "lib-conf.cf", #. User configurations "lib-core.cf", #. System variables and library functions "cf-agent.cf", #. Starting point for cfengine clients & servers "cf-serverd.cf", #. Cfengine server configuration }; -Dan _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
