Worst Linux Annoyances?

greenrd writes "Ever spent hours trying (and failing) to get a printer driver to work on Linux? Struggled to configure something ever-so-slightly out-of-the-ordinary? What have been your biggest annoyances when using Linux? Three O'Reilly authors are compiling a book on Linux annoyances - and their suggested solutions - and they've started a mailing list here. I can't help but think, though, that such a book will be dated quite quickly. Sure, some problems do languish unfixed for years - but equally, I suspect many of the problems will be fixed before, or soon after, the book's publication date. Still, increased visibility might motivate developers to create fixes or workarounds for some of the problems, so maybe this is an ideal opportunity to get your pet peeve finally addressed!"
