Any plans to do a version of the book focussed on my favorite distro (that isn Ubuntu)?
Ubuntu has the biggest user-base right now, and therefore the biggest potential readership. In blunt terms, we fish where the fishes are. But we monitor the distro marketplace closely, and have years of experience of Linux. It should be pointed out that Ubuntu Pocket Guide and Reference is still largely relevant for virtually any distro that’s based on Debian, uses bash as its default shell, and features the Gnome desktop (although the latter isn’t too big an issue). This includes versions of Linux Mint, and gOS, for example.
