Hello, I would like to multiboot my raspberry pi 3 with the option of
raspbian and 9front. I don't even really need 9front's filesystem, as
currently I network boot off my 9front cpu server. Is there a good way
to do this? Is there a bad way to do this?

The real question is -- how do you want to trigger one or the other?
Do you want it to happen from the serial console during boot?
Graphical? By shortening a GPIO pin? Something else?

Thanks,
Roman.

i think you can even use 9front to /dev/reboot into linux :)

this would mean the linux kernel could even be dp9ik authenticated and
coming from the 9front fileserver

Is this really possible? That would be awesome!

Thanks,

Install raspbian on one sd card and 9front on another sd card.  Insert
the card corresponding to the OS you want to boot.  Dispose of the
raspberry pi in accordance with local e-waste ordinances.

> Is there a bad way to do this?

Every other conceivable approach.

on a real computer you'd likely just use lilo or grub to select either
the 9front or linux kernel.
but on a rpi without a real bios, i don't know. i bet khm is right and
switching sd cards is the easiest route

I know there is a multiboot loader for rpi, I just can't remember the 
name. Iirc it was also helping installing various linux distributions. 
There's a hole system around it (like, a windows application where you 
can select the distributions you want and configure the bootloader, then 
burn the whole thing to disk)

It's called NOOBS (new out-of the box system), and it allows to add 
custom OSes with a partition and a custom filesystem. Here's the github 
page which explains a lot: https://github.com/raspberrypi/noobs

u-boot can be a fine multiloader on RPi4 -- that's not a problem. The
problem is how the OP wants to control it (e.g. u-boot has a limited
way of being controlled)

Thanks,
Roman.

Well... the route I'm attempting is BerryBoot currently. The problem
is creating an image for it. It is fascinated with squashfs... I'm
honestly not sure if anything not linux runs on it yet. As we speak
I'm using a utility to try to convert the 9front image to it... I'll
be happy if anything about it works. If I can get it to netboot off my
local cpu server even I will be happy.

cinap sent a patch to the kexec people so rebooting into 9front should work

wait, this was on 386/amd64. arm/arm64 has no multiboot afaik,
so i dont know if my patches would apply here.
