This highlights a lack in our docs, I believe
Core is not even close to being as complicated as many other distros, but it does have many nice tricks like that. If even experienced users like coreplayer2 find new old things, that to me says docs aren't up to snuff.
If only there was enough time
I've had this idea of writing a book on Core, fully current for one release, with chapters describing the internals, some on projects to use Core for, some focusing on boot time etc. I was thinking both the pdf and ascii sources would be freely available online, dead tree version available at some cost.
Sadly, at least 'til christmas uni is taking all of my time, weekends too.
