bootchart2 \- collects and analyses data from boot process

After install simply add these options to your kernel command line, normally in \fI/boot/grub/menu.lst:
.in +4n
.B "initcall_debug printk.time=y quiet init=/sbin/bootchartd ..."
Then after bootup run pybootchartgui to get an interactive
chart rendering tool.
If you want to chart the initrd, add
.in +4n
.B rdinitrd=/sbin/bootchartd
to the kernel command line.
To make bootchart2 work best, please ensure your kernel is

If you want to start bootchart2 in a dracut (version >= 008)
initramfs, you have to change
.I init=/sbin/bootchartd
.I rdinit=/sbin/bootchartd
and regenerate the initramfs with bootchart support with:
.in +4n
.B "# dracut -f -a bootchart"
.BR pybootchartgui (1),
.BR bootchartd (1)
