As I understand it, it will reevalute the class promise, and therefore
check for the file's existence, on all three iterations. A good way to
see what is happening is to run cf-agent in verbose mode (cf-agent -vK)
and write its output to a file then read through it. You'll see lines
like this (yours will be prefixed with something other than "nova>"):
[r...@rhn ~]# cf-agent -vK > /tmp/out
[r...@rhn ~]# grep '^nova>.* in bundle .* ([1-3])' /tmp/out
nova> vars in bundle def (1)
nova> classes in bundle def (1)
nova> vars in bundle def (2)
nova> classes in bundle def (2)
nova> vars in bundle def (3)
nova> classes in bundle def (3)
nova> vars in bundle update (1)
nova> classes in bundle update (1)
nova> processes in bundle update (1)
nova> commands in bundle update (1)
nova> files in bundle update (1)
nova> services in bundle update (1)
nova> vars in bundle update (2)
nova> classes in bundle update (2)
nova> processes in bundle update (2)
nova> commands in bundle update (2)
nova> files in bundle update (2)
nova> services in bundle update (2)
nova> vars in bundle update (3)
nova> classes in bundle update (3)
nova> processes in bundle update (3)
nova> commands in bundle update (3)
nova> files in bundle update (3)
nova> services in bundle update (3)
nova> vars in bundle dg (1)
nova> classes in bundle dg (1)
nova> vars in bundle dg (2)
nova> classes in bundle dg (2)
nova> vars in bundle dg (3)
nova> classes in bundle dg (3)
Note how it does 3 iterations of the promise types in bundle "def", then
3 of bundle "update", etc. ("dg" is a custom bundle of mine).

thanks for the fast response.
it helps, i thought this is a recommendation :-/ (i should read more
exactly)
but one question i still have:
if i define a class:
classes:
"xy_installed" expression => fileexists("/usr/example");
does it recheck this value each time i use
xy_installed::
or only once at the beginning of each of the 3 times?
regards
nicolas
