[yocto] How to run script before mount rootfs

[Szabolcs Báder]

Hi,

I created for Raspberry Pi a simple OS-boot-switcher. I change a param from
rootfs, reboot and new OS run. I would like to add to for this flow a
parameter to create ro boot and rootfs.

I would like to read this parameter at boot and depend on this choose which
OS will load. How could I define this at boot (eg. from cmdline.txt or with
a shell script or load c code ..?). What is the best idea/ way to do that
within Yocto?


Thanks in advance,
Szabolcs
