boot time

with 3 comments

bootchart is a nice tool to help you visualize your boot process. it creates a new .png file under /var/log/bootchart each time you reboot your machine…

a lot of people are working to speed up linux’s boot process:

this is interesting, and i will be adding links here as i find them…

  1. some days ago, the regular fsck check was started while booting to scan my 500gb harddisk, which takes quite a while. bootchart was running in the background all the time. after 3 or 4 minutes, it had filled my boot-partition, and my screen was full of error messages.

    so better don’t combine bootchart and fsck on startup.

  2. hi danilo, bootchart saves in /var/log/bootchart
    unless you have a separate boot partition, /boot is in your root partition

    you should always leave at least 1GB free in your /, not only for cases like this, but also because low disk space increases non-contingency, which makes disk access times rise…

    to make sure this never happens to me, I either have a separate /home partition, or I don’t save almost anything in my home dir…

    PS fsck in ext4 will be much faster…

  3. hm, i just realized that my /boot is on my fedora partition (which i don’t use anymore, i just use it to load the bootloader). 103G free. my gentoo / has 68G of free space.

    i don’t know what the problem was, i can’t think of a situation where logs or a bootchart should fill 68 gigs of disk space… strange.
