From 9aac4a0b4372d5e3db573641cc1e5a44e3748b0b Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 26 Nov 2018 15:43:22 +0100 Subject: [PATCH] EFI: don't repeatedly replace symlinks Once created there's no point re-creating them on every incremental make. This in particular prevents them from becoming root-owned during e.g. "sudo make install-xen", but it also allows (during development) to replace them there (instead of in common/efi/) by actual files with perhaps slightly changed contents.
