Hi -- I tested this on a fedora box and it fixes the issue. LGTM. |
In order to work around cases where we are replacing a file we don't have write access to in unprivileged mode (as well as to clarify the hardlink semantics of unpacking), always remove the target path (unless it's a directory) before unpacking over it. As we always re-apply metadata this should not cause any issues. Signed-off-by: Aleksa Sarai <asarai@suse.de>
This is to ensure we don't regress on file clobbering when we don't have write access to the target file. Signed-off-by: Aleksa Sarai <asarai@suse.de>
