Are you using a new version of Cfengine? I seem to recall having some issues with the CF_NULL entry in slists not always getting purged in older (as in, prior to 3.1.5) releases. So instead of skipping an empty element in a list, I'd end up having one iteration with an empty element. In this situation, though, your command might also be emitting a newline when it doesn't find any results. I'd check for that. If you can't prune blank lines from the command's output, you might try using splitting into a temp list and then using the grep function to pull out only entries which match \w+. In any case, I'd be inclined to define an additional class like "hasfile_$(virt_disk)" based on the result of a fileexists expression, and use that in the ifvarclass line to make sure you only operate if the file exists - or base directory, whichever is apporopriate. I'd also be inclined to use the readfile function instead of putting cat inside of an execresult, BTW. ;) _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
