From f8d4db54db8f2ab2c7f99f0fcbc456177d33ddad Mon Sep 17 00:00:00 2001 From: Jan Gutter Date: Tue, 26 Sep 2023 21:37:32 +0100 Subject: [PATCH] zun: Deprecate Zun provisionally * Zun currently has a dependency on a combination of Docker and etcd that is no longer installable (or supported) in newer distros. * These components are core dependencies of other systems and vendoring them will be very painful. * Work to update Zun past this is scheduled for the 'C' cycle. * If Zun regains compatibility, backports to this series will be considered.
