Heya,

The suggested way to run boot chart is by specifying
init=/usr/lib/systemd/systemd-bootchart on the kernel cmdline. What's
the rationale behind making this a service? I mean, if it is started
as service it races against other services and might thus not be able
track services run in early boot. Can you please elaborate on the
rationale for this patch?
