This week's Hug Day will focus on Casper! The goal of today's bug day will be to make a LiveCD boot without intervention and make many people's first impression of Ubuntu rock!
Here we have a sampling of bugs to work on for Hug Day. After you have triaged or fixed a bug put your name in the last column and set the row's background to green by adding lightgreen in the first cell of the column after "background-color:" and before ";". This will let people know that the bug in that row has been hugged.
5-a-day-ing
During hug days you can also do 5-A-Day for this one you can do the following in order to tag your work on the hug day:
- 5-a-day --add-tag hugday-20080814
- Add bugs to 5-a-day as usual
- And when done with hug day run: 5-a-day --remove-tag hugday-20080814

casper and kernel log files
For debugging casper please boot with the boot option (e.g. kernel line in grub or append line in isolinux) "debug=". At the live CD boot menu, press F6 and add debug= to the list of parameters:
append file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.gz debug=
Removing quiet and splash is generally a good idea when debugging. See example screenshot.
The debug log file is /casper.log inside the initrd temporary filesystem, but will be copied to /var/log/casper.log in the fully booted system. The kernel log will be in /var/log/dmesg.log. If the system does not boot up, retrieving the log files for attaching to the bug report can be an exercise of its own:
- plug in an usb stick
- watch the kernel messages and look for the partition on the stick, for instance /dev/sdb1
or check with ls /dev/sd* if you can recognize it
mkdir /tmp/stick
mount /dev/sdb1 /tmp/stick
cp /casper.log /tmp/stick/
dmesg > /tmp/stick/dmesg.txt
umount /tmp/stick
- unplug the stick and give us the files casper.log and dmesg.txt!
Failing this, a photograph of the screen (hopefully with some relevant error messages) can be of help.
