Use Runlevel 5 instead of Runlevel 3

Hi All, What i have to do that linux starts with runlevel 5 after autoinstallation. On my installation it starts allways with runlevel 3. I have allready tried this: <runlevels> <default>5</defaults> ..... </runlevels> ****** <runlevels> ..... </runlevels> (without default TAG) Thanks! bye Alexander
