Fedora will boot off what ever storage the firmware supports, it also
depends on where you expect the firmware to resided.
As far I understand [1] uboot cannot read from SD card because it's attached
behind an USB hub.

Not sure what kexec provides in this context.
My idea is:
1- Install Fedora on a SD card partition using virtualization
2- Insert SD card into L5 slot
3- Boot L5: the PureOS system will be loaded
4- Open a terminal as root
5- Use kexec to boot the Fedora kernel from SD card
Unfortunately [1] it seems that kexec doesn't work.
A different way has been proposed: configure an alternative
boot using an environment variable. Not very simple indeed.
Thanks
