Hello and happy Tuesday!
As those of you who are active on Slack already know, Daniel and I are trying to reboot the LinuxBoot project, which after many successful years hasn't seen much public activity recently. We are hoping to generalize the project with a focus on the idea of LinuxBoot rather than just the build system or any one specific implementation.
Promoting the idea means writing common documentation so the lessons learned from the past do not need to be re-learned or lost to time. Additionally, problems common to all implementations like hardware state during kexec or managing kernel configs can be solved collaboratively.
Both linuxboot.org and book.linuxboot.org have already seen some significant updates, but there is still plenty of work to be done. If you have worked on a LinuxBoot implementation we'd greatly appreciate contributions to the book describing the project and linking to any applicable documentation. If you've given a presentation consider adding it to the list.[2] Any clean-up commits are truly priceless and would be greatly appreciated!
I have CCed everyone who attended the first meeting last week. For those who are not on the mailing list please join.[1] If you have trouble ping me and I can add you manually.
I've also added David from Google, Warner from FreeBSD and Benedikt who lives in Bochum near Daniel and has already made a contribution to the book! Thank you!
I'll follow-up with an invite for next Monday 2PM CET, 8PM China/Perth, 8AM New York/Toronto. For now we'll plan on bi-weekly meetings. If there is interest from the west/central U.S. we can also schedule an additional meeting.
Best,
Philip

Thanks David, these are all great points. My hope is that we'll clarify them in the next month after we've had a few meetings. During that time we'll work on the book, establish the role of the Linux Foundation, and hopefully increase participation.
My current hope is that once the book is a good resource to explain what LinuxBoot is, how to implement a LinuxBoot boot loader and provide a reference for common online discussions (e.g. Why UEFI is not the answer?), then we can start promoting the idea broadly on LWN, Phoronix, conferences, etc to try to get more participation.
That will hopefully bring together the fractured ecosystem and allow us to learn from past efforts. It will also make it much easier to implement a LinuxBoot for any given use case. To make LinuxBoot truly relevant though I believe we'll need a boot chain distribution. But that's a whole new topic. :-D
