The samba book is installed twice, in /usr/share/doc/samba... and in /usr/share/swat. Could you make samba_book a sub-package of the samba srpm and install it just in 1 place? You can install it by default in /usr/share/swat if you like, just to make the /usr/share/swat/help/welcome.html link ok. People who prefer saving space (2.8MB) can uninstall it.
