I don't think it would be all that great if you need to do a full reboot each time for the changes to take place like that sites suggests you have to do.

It doesn't seem like it would be worth such a constant hassle.

Whenever I add a new font, in Xterm I do

root
fc-cache -fv
/etc/init.d/maemo-launcher force-reload

From there any new font is immediately available to be selected in Xterm.

So would a reboot be required for this?
