===== Visualizing the boot process =====

Bootchart is a tool to create a chart of the boot process. It can be used to pinpoint the slowest parts, or to prove one's distro's boot speed.

Using it always requires a remaster. If you don't know what you're doing, read up on [[Remastering|remastering]] first.

==== # ====
First, download the tarball:
ftp://distro.ibiblio.org/tinycorelinux/2.x/tcz/src/ubootchart/ubootchart.tgz

The source is in the same directory, if you wish to take a look.

==== # ====
Extract to the initrd:
^sudo tar -C /tmp/extract -xvf ubootchart.tgz^

==== # ====

Replace every "sbin/init" with "sbin/ubootchartd" in /init:
^sudo sed -i 's@sbin/init@sbin/ubootchartd@g' /tmp/extract/init^

==== Deciding when to stop logging ====

... and add **sudo killall -USR1 ubootchartd_bin** to /etc/skel/.profile before startx.
Or if you wish to add X in the mix, in a suitable place to stop logging.


===== Rendering =====

After boot, wait a bit for ubootchart to finish logging, load the bootchart-pl.tcz extension, and run it:
^bootchart.pl > /tmp/my_bootchart.svg^

If you wish to convert it to png, use rsvg-convert from librsvg.tcz.
