Consider the following example
bundle agent createfolder {
files:
"/home/nicolas/foo/."
create => "true",
comment => "Creating directory",
classes => if_else("foldercreated", "failure");
commands:
foldercreated::
"/bin/echo \"Folder created or present\"";
failure::
"/bin/echo \"Failure\"";
}
body classes if_else(if, else) {
promise_repaired => {"foldercreated"};
promise_kept => {"foldercreated"};
repair_failed => {"$(else)"};
}
It should create the folder foo if it doesn't exist, and set the class
foldercreated. But it doesn't (latest trunk build and cf3.0.2)
Output if folder doesn't exist :

Using "/home/nicolas/foo/" as a temporary workaround: it failed for it
is not a file, but a folder, and at the next iteration the folder is
there, so the promise is kept
