From 8f852648fe730615c99bcdaace8a4748ef4e96a5 Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Fri, 28 Oct 2022 16:23:53 +0100 Subject: sanity: check for GNU tar specifically We need the system tar to be GNU tar, as we reply on --xattrs. Some distributions may be using libarchive's tar binary, which is definitely not as featureful, so check for this and abort early with a clear message instead of later with mysterious errors.
