[pve-devel] [PATCH pve-cluster v2 1/1] notify: add common_template_data

[Lukas Wagner]

This commit add the `common_template_data` sub to PVE::Notify,
providing a convenient way to get a hash with properties that
should be accessible from all templates, namely hostname, fqdn
and cluster-name.

Notes:
    Changes since v1:
     - use PVE::Tools::get_fqdn instead of using `hostname -f` subprocess
       to get the fqdn (thx @Thomas!)
