Validating your Munki manifests and pkgsinfos

Sometimes, bad things happen to your .plist files. Thus, it is prudent to run the following check on your Munki repo before deploying into production:

find {manifests,pkgsinfo} -type f -exec xmllint --output /dev/null {} \;

This will find all the files under the manifests and pkgsifo directories, check them for well-formedness (but not content; you might still have a typo in what you actually want to say!), and report only on the errors.

The output is sent to /dev/null, as xmllint would otherwise spew out all valid plist files to the terminal, effectively hiding any problems you might have had. A --quiet|-q option would have been cleaner...
