From 6f7ee71165b30272a4f18bca361c324c7671680c Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Fri, 3 May 2019 23:33:41 +0200 Subject: unsquashfs: add flags to filter what file types to unpack This allows the user to skip stuff like device special files (which non-root can't create anyway) or to not create symlinks/fifos etc...
