Bug Description

This is a placeholder bug for the work mfisch is doing (going to do) to fix bootchart and make it work "out of the box". Once I get back to this, I'll post more details on what's wrong and how I plan to fix it.

So I was able to eventually get bootchart to create a png and a tar for me. What I had to do was edit line 33 of /etc/init/bootchart.conf. I changed it from:

    if [ -d /dev/.bootchart ]

to

    if [ -d /dev/.bootchart/log ]

As /lib/bootchart/gather was failing, because /dev/.bootchart/log didn't exist for some reason. I don't know if there's an easier way to let users do this, but I'll continue investigating. In the meantime, I'll upload some bootchart info

We should ensure we get a proper upstream fix for this in R.

I'm not sure this patch makes much sense. If the initramfs script is failing to create the directory, it's also going to fail to produce logs in the directory, after all, and perhaps one should hunt down why this is...

Also, in looking at the bootchart initramfs script, it's going to fail on armhf, since it's not copying the armhf linker into the chroot jail. Were these tests on armel or armhf?

Adam,

The initramfs script is failing altogether, as it is an armhf device. This upstart job seems to only run if that initramfs script doesn't run, and it fails to create the correct log dir without this patch.
