It has treatment of the whole spectrum of issues including making proper patches, the freedesktop.org menu specification, and ancillary files like logrotate.d files,/etc/cron.*/ files, creating SysV init files and chkconfig.
One unique thing about the guide is that it is not just a reference as it includes a very detailed (48 page) lab exercise that walks a would be
packager through several real world scenarios.
The lab exercise has been validated and tested to "just work as written"
on the following distributions:
Fedora Core 3
Red Hat Enterprise Linux 4
SUSE Linux Professional 9.2
SUSE Linux Enterprise Server 9
It will likely work, possibly with small modifications, on other RPM
based distributions as well.
The guide can be found under the "Goodies" section of our website here:
We are excited to make this release and hope it is useful addition to the available RPM documentation and helps increase the amount of quality
packagers and packages."
