[pdm-devel] [PATCH datacenter-manager v4 15/23] ui: pve wizard: info: detect hostname and fingerprint

[Dominik Csapak]

Instead of always inserting the initial host into the nodelist
(which will always be duplicate since it will be also contained in
the node list), try to match the hostname and or fingerprint with
any of the given node, so we can deduplicate that.
