	I would've thought that putting the shellcommands in x.cf and 
then importing x.cf after linux.firstrun.cf would solve it.

        To quote the reference manual:
"Note that, if you define variables in an imported file they will not be 
defined for operations in their parent files. This because cfengine reads 
in all the import files after the main file has been parsed\u2014not at 
the place where you call import in your script. This means that variables 
or macros defined in imported files are only defined after the main 
program. Variables from earlier files are inherited by later includes, but 
not vice-versa."
