I just noticed that the mail command is missing on labsdb hosts, which is used to report if there is any private data there.
However it is on sanitarium hosts (where we use it for the same reason).
On sanitarium hosts we have bsd-mailx installed, and on labsdb this has been working fine for years, but I cannot see the package anymore, so maybe when the role changed it was removed.
Rather than installing it on a per-role basis, maybe we should just ship it on standard_packages.pp (as per my chat with @Muehlenhoff).
The mail command is useful to have and definitely critical for our labsdb hosts.
