The document title "Gentoo Linux 1.4_rc2 Installation Instructions" does not match "The Gentoo Linux CD Installation Guide" (used both in bugzilla and on (http://www.gentoo.org/main/en/docs.xml). Consider revising "Gentoo Linux 1.4_rc2 Installation Instructions" (the in-document title) to ""The Gentoo Linux CD Installation Guide for 1.4 RC2" to avoid a needless proliferation of names.
This will change when the final 1.4 is released. The doc will have the name Gentoo Linux 1.4 CD Installation Guide.
