I put this at the end of the init.m, outside of all other expressions

$GuideBooksTOC =
"/usr/share/Mathematica/AddOns/GuideBooks/TableOfContents.nb"

, and when Mathematica starts it behaves as if I had done `mathematica
-cleanStart'. Even before I close Mathematica, `cat init.m' shows
SetOptions[$FrontEnd].  With no new line at the end of the file, I will
add.
