Re: Setting variables based on classes in an imported file

[Paul Krizak]

As far as I know, cfengine does imports *last*.  That means that despite 
your import statement being at the top of your file, cfgroups.conf isn't 
actually imported until after the containing file is parsed.

Luckily, imports *are* imported serially, so you can get around this 
restriction by adding yet another wrapper.  For example:

update.conf:

import:
  any::
     cfgroups.conf
     real_update.conf

Then put all the "guts" of update.conf into real_update.conf. 
cfgroups.conf will then be processed before real_update.conf.
