We have a mix of root and non-root containers, and are trying to become rootless. This can cause the local CPIO fragements to end up being user:user in the test environment. Nothing seems to go wrong so far, but it's a trap waiting to happen. Make everything consistently root for the initrds, irrespective of the rootness of the container the test is running in. No practical change. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com> Reviewed-by: Denis Mukhin <dmukhin@ford.com> Acked-by: Stefano Stabellini <sstabellini@kernel.org>
