The latest version of lilo forces TABLE and UNSAFE options mutualy incompatible. It is not possible to avoid a sanity checking of a valid boot signature of the first sector of an ordinary partition. This was not the case in some older versions. This feature causes a lot of problems for special installation procedures where somme operating system is installed later and so on. This sanity checking should be optional.
define 'latest version' if that applies to 22.6, then please re-open
