An example: add the following to
<puppet_path>/modules/<modulename>/lib/facter/augeas_available.rb
-- cut here --
require 'facter'
Facter.add("augeas_available") do
setcode do
avail = "no"
Dir.glob("/usr/lib/libaugeas*") { |filename|
avail = "yes"
}
avail
end
end
-- cut here --
It simple looks for files named /usr/lib/libaugeas*. I am not sure if that
is appropriate for CentOS too, but it works on Debian. Of course, this is
no guarantee that the Ruby-bindings are also available, so this is still
not idiot-proof.
After installing the fact, you can do something like this in a manifest:
if $augeas_availabe {
augeas { "foo":
}
}
Best regards,
