superseded by systemd-bootchart, remove after no form factors use upstart as pid1

[Bryan Quigley]

Bootchart currently does not work if systemd is the init system. This prevents us from comparing boot speed from upstart vs systemd. (It also might make other bugs more visible). The provided init.d script doesn't work.

bootchart2 (in debian) does have systemd unit files available but they are not drop in replacements for bootchart(1).

There is also a bootchart built in to systemd? That might also be a useful option.

I'm on Ubuntu Utopic with bootchart 0.90.2-8ubuntu2. (Was originally looking at in https://bugs.launchpad.net/ubuntu/+source/bootchart/)

[2016 update]
In light of current status of Ubuntu form-factors - I'd like to keep this in until after none of the form factors use upstart as pid1. At the moment, ubuntu touch does. And it might be likely that e.g. ubuntu touch will use xenial with an underlay ppa, still with upstart as pid1.

Status changed to 'Confirmed' because the bug affects multiple users.

You can get a bootchart on systemd with the following command `systemd-analyze plot > plot.svg`

I'm nobody, so feel free to unset the invalid status if that doesn't solve your issue.

@Daniel,,
You're not nobody. that was incredibly helpful! Per the blog post you posted I'll be able to do what I was hoping to do. Although per the same blogpost, bootchart still has some useful advantages over the systemd way..

systemd-analyze plot is a very reduced form of bootchart indeed, but has the advantage that it's always available. OTOH, systemd has "systemd-bootchart" built in which needs to be activated manually as it slows down the boot due to the probing (like the original bootchart). But it's very easy -- boot with init=/lib/systemd/systemd-bootchart, and pick up the SVG from / run/log. (See man systemd-bootchart).

This shows all the information that the old "bootchart" package did (it's built on top of that and got developed further). So I think we don't need to bother about adding units to this package, and should instead just remove it once we switch over to systemd as a default. Do you agree?

[Bryan Quigley (bryanquigley)]

Agreed, awesome. Closing.

[Martin Pitt (pitti)]

Still keeping it open as a reminder to remove the package.

https://wiki.ubuntu.com/BootCharting should be updated with the new info too

[Martin Pitt (pitti)]

@Oli: Indeed! Done
