<josem> one limitation is, if any FMP instance is installed and then
uninstalled during the same boottime flow, the ESRT entries will not be
removed
<josem> this limitation is because I cannot find a proper UEFI way to
hook to a FMP protocol uninstall.
<xypron> register an event with RegisterProtocolNotify().
<xypron> EFI_CALL(efi_register_protocol_notify(...)) after exporting the
function in /include/efi_loader
<xypron> The event can be created with efi_create_event().
