in /Library/Preferences/SystemConfiguration you may find a file named com.apple.Boot.plist

the content looks like

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
   <key>Kernel</key>
   <string>mach_kernel</string>
   <key>Kernel Flags</key>
   <string></string>
   <key>Boot Graphics</key>
   <string>Yes</string>
   <key>Timeout</key>
   <string>2</string>
</dict>
</plist>

 

when you change

 

<key>Kernel Flags</key>
<string></string>

 

to

 

 <key>Kernel Flags</key>
 <string>[b]-f[/b]</string>

 

your system will always start with the option -f

 

to edit this file simply copy it to your desktop, open it from the with textedit, do your thing and then copy the file back from where you get it. (authenticate if necessary)
