We highly appreciate everybody who spends time helping us to find bugs and fix them. This public beta is in addition to the internal beta program which started some time before we made the 6.0 beta available on our FTP server. The public 6.0 beta is quite stable already and we don't expect to have major bugs to fix. Most of the bugs found at this point will be minor things, which can be fixed quickly. The Linux business requires acting within a very fast-changing environment.
Nobody can afford to have long periods of beta testing.
If you take three months for testing, the distribution will be already outdated when it reaches the customer. If it should be the case that somebody finds a major flaw in the current beta, we will delay shipment. However, nobody at SuSE expects this to happen. Then, we are asked to boot with this floppy and choose the FTP installation. You are right.
