In this commit, we are ensuring the dirs in the `/` root path of the temproot is as close as the 'real' one as possible. `$SANDBOX_DIR/temproot` is now being created with the same permission as the host, and every other directories on the top level are created with the same mode as the real one. Symlinks are now also created in the unshare, and removed after unshare finishes. Tests are created to check the mode, ownership, and symlink of the files in the `/` directory. Known issues In the test, we're ignoring files with the name swap. And also /proc, our current `mount -t proc proc /proc` invocation are creating the /proc dir with nobody and nogroup ownership. We're tracking this in #151 This PR currently assumes there are no regular files in the root dir besides the swap.img. We're tracking this in issue #150 * feat: keep toplevel dir perms in temproot - fixes #80 * feat: recreate symlinks in temproot - fixes #139 * feat: set correct permission for root dir, and remove symlink after unshare * feat: set temproot to be writible before removing symlinks * test: add new test to verify consistency of root dir (see known issues) * test(reuse_problematic_sandbox): set test to use a non-symblink dir * test(toplevel-perms): ignore acl bit, user&group ownership
