Part of the problem is that no-body know the best method to handle this in a multi-user environment, and still provide security. So different methods are being tried, hoping that the best method will be found. To complicate things, the best method for the desktop is probably not going to be the best method for servers. If you are doing remote access, that adds another complication. Then you have remote file systems that need to be mounted. Another part of the problem is that hardware has advanced. Just look at the speed/capacity of flash memory. I can buy a 2G memory drive now for less then I payed for my first 32M memory drive. Methods that worked well when people only had one or two memory drives do not work well any more. Linux is adapting to the changes, but it isn't always smooth. With Fedora, you will probably hit more bumps because the nature of Fedora is to try new things. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
