Wrong assumption here. Often drivers etc. gets patched with "need single user mode", which are not used by the system at all (e.g. fc). So the admin says, don't care and go ahead - don't wanna take the system out of service... > How about: > > A.

If so, please do not forget to add an option, which lets the sysadmin ignore this IMHO often invalid "requirement" ...
