ok im using the guide from
http://www.gentoo.org/doc/en/prelink-howto.xml and trying to set up prelinking in slack 10.0..i reached upto the point where im supposed to
Speeding Up KDE After Prelinking
KDE's loading time can be greatly reduced after prelinking. If you inform KDE that it has been prelinked it will disable the loading of kdeinit (as it isn't required anymore) which speeds up KDE even more.
Set KDE_IS_PRELINKED="true" in /etc/env.d/99kde-env to inform KDE about the prelinking.
my question is ...where is this damn /etc/env.d/99kde-env file in slack???/
thanks for the help in advance
