Why does Ubuntu create the file /var/log/boot?

  • 772

Why does Ubuntu 10.04.4 and 11.10 create the file /var/log/boot and does not fill it except with the text: "(Nothing has been logged yet.)"?

  1. The reason it is empty is that bootlogd is disabled by default.

    If you wish to see boot messages in the log you need to enable it.

    Do Alt+F2 to open Run Dialogue

    enter image description here

    Then Change

    BOOTLOGD_ENABLE=No

    to

    BOOTLOGD_ENABLE=Yes

    Save and exit gedit.

    This is what it looks like here - decide if the information is important to you and enable if you wish.

  2. You need to enable boot logging by opening a terminal and typing the following:

    $ sudo gedit /etc/default/bootlogd

    The text editor will open, and the following will be show:

    BOOTLOGD_ENABLE=No

    Change BOOTLOGD_ENABLE to yes

    Now, everytime you restart, /var/log/boot will be created, and it will contain a log of all your boot messages. You need to be root to open it, so you can easily open it up again with sudo.

  3. If it's not installed by default:

    apt-get install bootlogd

    Then make sure /etc/default/bootlogd has BOOTLOGD_ENABLE=Yes.
