They have "improved" the installer in Fedora Core 5.
Now after the package selection it says "Starting installation process", cricks the DVD drive for about 5 minutes, then says "Transaction failed: not enough disk space" and *surprise surprise* just reboots. Filed bug #187656.
They have also "improved" Release Notes in installer.
There is a nice hyperlinked table of contents at the beginning of the document, and then you put your mouse pointer over the link, the pointer shows as a hand with index finger pointing. That gave me the sense that I can click on that link. No I can't. Well I can but it does nothing. Filed bug #187658.
They (or is it GNU coreutils team? or glibc team?) have "improved" cp as well: wrote about it before. Still have no time to fix it. :(
