From 463bc7b82e7b3e8298d9cb81b5d03af8b48b2148 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Thu, 21 Nov 2024 15:32:07 -0700 Subject: test_fs: Allow running unprivileged There is no need to mount the filesystem on the host side. All filesystem tools offer some way to fill the fs without mounting. So, create the content on the host side, create and fill the fs without mounting. No more sudo or guestmount needed. This new approach works because the tests don't care about user IDs and no device files are needed. If user IDs start to matter it's still possible to use wrapper tools like fakeroot in future while filling the fs.
