Re: Dangerous Software Raid instructions on Wiki

[Bassu <bashukhan@xxxxxxxxx>]

I would agree with Max. Doing things you don't know requires you to have a bit of knowledge before proceeding like warnings in a few configuration files to not to go ahead and doom your production systems if you clearly don't understand what any configuration may have been for. 

It said what it did and Chan, you don't need to obviously show your rudeness to a public mailing list.

The document's first sentence clearly states the purpose of the document:

"This article addresses the setting up of a software (mdraid) RAID1 at
install time on systems without a true hardware RAID* controller."

The part being important here is "install time." So I think it's pretty
clear. Is it the document writer's fault that other didn't read this
part? I don't think so.
