From 892ba8c3cc0617d2087a2337d8c6e71524d7b49c Mon Sep 17 00:00:00 2001 From: Christian Hesse Date: Wed, 26 Feb 2020 09:12:21 +0100 Subject: ui-snapshot: add support for zstd compression This patch adds support for zstd [0] compressed snapshots (*.tar.zst). We enable multiple working threads (-T0), but keep default compression level. The latter can be influenced by environment variable.
