[1] what i would like to know, (if someone can take the time explining it to me) is what are the reasons, if any, this can't be done by default. My steps are simple: 1) Disable services i am sure i wont use, like: laptop- laptop-mode, apmd, pcmcia... printing - hplip, cupsys... bluetooth raid - mdadm 2) Start many of the services asynchronously. i know i am probably stretching the line in some services, but it boots just fine. on the other hand, some of these are begging to be run in async mode: one such example is hwclock that takes over 2 seconds to sett the clock Following these steps, and with included startup for restricted modules (nvidia driver) i got my boot down to 18 seconds, wich is about 1/2 of the original time. Also Interesting to note is that detecting my single sata disk and cdrom seems to take almost 5 seconds of that time. -- João Inácio <a href="mailto:jcinacio@gmail.com"> jcinacio@gmail.com</a> -- ubuntu-devel mailing list <a href="mailto:ubuntu-devel@lists.ubuntu.com">ubuntu-devel@lists.ubuntu.com</a> <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel">https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel </a> </blockquote></div>
