Hi @misc Today I was trying to delete EFI variables and got EPERM.
After some investigation I found at efi.c the below code efiioc_var_set(struct efi_softc *sc, void *data) ... if (securelevel > 0) { error = EPERM; goto leave; } So maybe a statement can be added to the securelevel(7) man page saying that setting and deleting (or simply changing? basically it's the same operation) EFI variables when securelevel is 1 or higher is not allowed. Regards.
