actually taking index.html out of the apache package would
make installing a new homepage easier.
if you still wan't to keep an index.html for RedHat Linux,
it should be located on the redhat-release package
the index.html file is marked as noreplace, so if you modify it
locally and then upgrade apache, you will not lose your changes.
even marked as %config(noreplace), it would unnecesarily show warnings
on an rpm check, if it is changed.
IMHO, index.html and powered.cgi are more relate to redhat-release
than to apache
taking manual out of apache for 5256, would need an scripted
modification of index.html to for not showing the missing link.
making a default index.html with a manual link seems to static for me,
there should be a better way to put a default "it worked" homepage
