This is not actually correct. I don't think that I did understand your question, as you had provided no context. Your question might have been: 1/ I was reading the man page and discovered that RAID5 is not=20 permitted with --build and wondered why. or 2/ I was reading the code and saw that RAID5 is not permitted with=20 --build and wondered why or 3/ I was trying to do XX and thought that --build might be a solution but I need RAID5 and --build doesn't support RAID5 - why is that? Each of these could have quite different answers so I couldn't be sure that what I would say would actually be helpful unless I answered all of them, which would probably be a waste of effort to some extent. This is why I fe= lt that "Because!" was about all that the question really deserved. I was feeling rather tired at the time which probably explains (without justifying) the shortness of my answer. I should have realised that and not replied at all - my mistake. BTW I wasn't intending sarcasm at all - sorry if you thought I was.
