<br></blockquote></div><br></div><div class="gmail_extra">If you want smaller kernel size, just avoid compiling modules or kernel component that you don't need. Things like unneccessary device support, protocol support are something you can begin with.<br><br></div><div class="gmail_extra">Also, once you do:<br></div><div class="gmail_extra">make<br><br></div><div class="gmail_extra">then if later you did modification on certain .c files, then next invocation of "make" will only recompile the changed .c files. if you need further speed, use ccache.<br><br></div><div class="gmail_extra"><br clear="all"></div><div class="gmail_extra"><br>-- <br><div class="gmail_signature">regards,<br><br>Mulyadi Santosa<br>Freelance Linux trainer and consultant<br><br>blog: <a href="http://the-hydra.blogspot.com" target="_blank">the-hydra.blogspot.com</a><br>training: <a href="http://mulyaditraining.blogspot.com" target="_blank">mulyaditraining.blogspot.com</a></div>
