After installing Win4Lin, `rc-update add Win4Lin default` could not find the Win4Lin rc script which is installed /etc/init.d/rc.d. The same applies to other apps like kudzu. My proposed fix is to the baselayout to create /etc/rc.d with a link to /etc/init.d in it: mkdir /etc/rc.d cd /etc/rc.d ln -s ../init.d
or why dont you make some Gentoo compatible init scripts for those packages ? those init scripts are not the same as a Gentoo init script ... edit them to see i'd suggest you file a bug for each
