From c2996b5fa880e81f63c25e80a4157b2239e32c5d Mon Sep 17 00:00:00 2001 From: Michal Suchanek Date: Mon, 10 Dec 2018 22:29:32 +0100 Subject: [PATCH 1/2] depmod: prevent module dependency files missing during depmod invocation depmod deletes the module dependency files before moving the temporary files in their place. This results in user seeing no dependency files while they are updated. Remove the unlink call. The rename call should suffice to move the new file in place and unlink the old one. It should also do both atomically so there is no window when no dependency file exists.
