The installer happily wipes all drives present on the system when doing a server install, but then proceeds to only use one of them. Perhaps this is not the best idea.
The installation manual clearly states that all disk space will be cleared. It may not be a good idea, (I nearly missed that fact when I read the book,) but I hardly think that one can classify a documented feature as a bug.
A recent negative evaluation of Red Hat mentioned this as one of the many stumbling blocks encountered during testing. See http://worldserver2.oleane.com/dmartin/Linux.htm#pgfId=1004 IMHO it's scary to know that the installer would do something so counterintuitive. Even if it warns the user, it's still dangerous. Everyone knows users don't read the screen...
Matt, do we still wipe all disks, but then only use one of them? If so, why? Please resolve this bug in some fashion, either with won't fix or fixed, and an explanation.
This bug is fixed in the latest version of the installer (available in beta)
