A quick test shows that that cfengine will actually canonify the string
automatically in this case. This is news to me, as I thought that it would
Aleksey is correct here - a string, which may contain variables to be expanded,
is interpreted as a class, and the promise is evaluated if the resulting
classname is true.
So if the variable "foo" contains the 3 letters "baz", then ifvarclass =>
"foo$(foo)" will allow the promise to be execut
Thanks for the correction, Seva, I certainly don't want to produce
a misunderstanding.
Reference manual states:
Cfengine 3 has a new class predicate ifvarclass
which is ANDed with the normal class expression,
and which is evaluated together with the promise.
It may contain variabl

Better yet, you can drop the file argument.

You need to use canonify, and then use the variable in a class expression.
Canonify ensures that the string only has characters that are valid in clas
Aleksey,
your statement sounds very new to me. IMHO, it may produce severe
misunderstanding.
The "ifvarclass" attribute does NOT allows one to treat a variable as
a class, it only allows to check whether different classes were
defined using a variable.

Hi, jordy. Also check out "ifvarclass" promise attribute -- it's for

Woohoo!!!
Of all places to find the answer for this, I found it on the man pages. :)
For anyone trying to get this to work, I did not change the cf file in this
trail. I just had to change the way I ran cf-runagent.
For completeness, here is the cf-serverd command I used.
