(whether as part of dracut or as part of a new dracut-extras package) This module is mentioned... http://git.kernel.org/?p=boot/dracut/dracut.git;a=tree;f=modules.d/00bootchart;h=f5f312657583ce98f6266c6b163baa81fb262006;hb=HEAD http://www.kernel.org/pub/linux/utils/boot/dracut/dracut.html#_adding_dracut_modules
Have you tested if it works at all? If so, OK. I'll probably add this as a new package: dracut-extras.
(In reply to comment #1) > Have you tested if it works at all? No, I'm not sure I have the skills needed to test it manually (unpackaged). But I would think that the module works fine (not just half-baked code) since (1) Dracut uses the bootchart module in their official documentation (as their first-and-only example under "adding dracut modules", see link above) and also (2) bootchart2 also includes instructions for using this dracut module in bootchart2's README file.
I have added the module to sys-kernel/dracut-018-r1 (without rev-bump). New flag should appear. Please test.
