Moreover we only install those if a CapsuleUpdate is requested. Since we now have an ESRT table, it makes more sense to unconditionally install the FMP, so any userspace applications (e.g fwupd) can make use of them and trigger an update. While at it clean up the FMP installation as well. Chapter 23 of the EFI spec (rev 2.9) says: "A specific updatable hardware firmware store must be represented by exactly one FMP instance". This is not the case for us, since both of our FMP protocols can be installed at the same time and are controlled by a single 'dfu_alt_info' env variable. So make the config option a choice and allow the user to install one of them at any given time. The overall changes show up in fwupd pre-patch: fwupdmgr get-devices No detected devices post-patch (with FIT FMP installed): fwupdmgr get-devices WARNING: Required efivarfs filesystem was not found See https://github.com/fwupd/fwupd/wiki/PluginFlag:efivar-not-mounted for more information.
