Re: actionsequence question

[Mark . Burgess]

I don't understand why you need copy before groups. If you want to
define groups as a result of copy use define= ?

Groups are just definitions, and cfengine does not guarantee the
ordering of anything unless you use define= 

This might be a job for AddInstallables ?
