Subject: Add PE facts to stdlib
X-Git-Url: https://gitweb.fluxo.info/?a=commitdiff_plain;h=cdf3b05f35f78971203dfd9fadd2552ad5a41bd4;p=puppet-stdlib.git

Add PE facts to stdlib

As many PE modules have PE specific functionality, but are deployed to all
nodes, including FOSS nodes, it is valuable to be able to selectively enable
those PE specific functions. These facts allow modules to use the is_pe fact to
determine whether the module should be used or not. The facts include is_pe,
pe_version, pe_major_version, pe_minor_version, and pe_patch_version. For PE
2.6.0 those facts would have values true, 2.6.0, 2, 6, and 0, respectively.

+# Resolution: Uses a regex match against puppetversion to determine whether the
