Re: [poky] Running chroot-like command in Yocto #yocto

I have no idea what this does, but MBR is not a file in the root
filesystem, it's data structure in the first disk sector.
Unfortunately I don't remember how legacy pre-UEFI ootloaders are
installed 'offline' during yocto builds.

Can you do this on target during first boot?

In debbos, I could do that using the following code and now I'm trying to reproduce that in the Yocto build system:
