From cca0ccaf97997691c492c490d263d2b98328af65 Mon Sep 17 00:00:00 2001 From: Toshio Kuratomi Date: Wed, 7 Mar 2018 17:14:51 -0800 Subject: Fix unarchive with strip-components in extra_opts (#37048) * Fix unarchive with strip-components in extra_opts When unarchive is given extra_opts to strip all leading directories, it could end up trying to change the permissions on the root directory. Tar archives shouldn't contain absolute paths anyways so make sure that all paths are relative as we handle them.
