Does the `/etc/servertype` file exist on the agent you're plugin syncing
to? If so, what are the contents? It might be that the newlines are
tripping up Puppet and Facter.
If you're only interested in the first line of the servertype file, you
could save an exec system call by reading the file directly in ruby, like
this:
# Replaces the `Facter::Util::Resolution.exec("cat /etc/servertype")` line
File.read('/etc/servertype').split("\n").first
Hope this helps,
