My experience has been that hardware detection is what slows boot process. I've tested on various distros, Red Hat Linux, Slackware Linux, SUSE, and Debian. Starting services never seems to take any time (noticeable time). But when it lands on detecting hardware, that's where the time is chewed. Typically with hotplug (all using 2.4 kernels) it's about 30 seconds, which is the same as the rest of the boot process in my testing lab. 1394, USB, and PCMCIA seem to be the slowest (because when I remove these devices or turn off detection of these types boot time is *much* faster). Two things that I believe should be addressed; 1) Speeding up boot time (even if that means moving some hardware detection and recognition to after login) -and- 2) Proper identification of filesystem types. Would love to have an agreed upon by majority change that would change the mounting of filesystems (identifying FS TYPE) to be more accurate. regards, -fd - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
