[PATCH] Language guide incorrectly uses alias in the host type where it should use host_aliases
Ticket tracking is now hosted in JIRA: https://tickets.puppetlabs.com
Since puppet-0.25.2, the host type has a host_aliases parameter for specifying host aliases. The example using alias appears to be incorrect. At the least, it’s likely to confuse new users and lead them to misuse the alias parameter when they should prefer host_aliases.
A patch is on the master branch of git://jet.mox.net/~tmz/puppet-docs.git.
