[00:50:49] <sivachandra> I have a change to the package sys-kernel/chromeos-kernel-next and would like to push a new kernel image to my Pixel device. How do I do it?
[01:03:17] <JoshTriplett> sivachandra: I assume you have verified boot turned off, so you can modify the root filesystem?
[01:04:08] <JoshTriplett> sivachandra: You want src/scripts/update_kernel.sh , which you can can run after building the kernel package from the target.
[01:04:45] <JoshTriplett> sivachandra: (Also, your target will need to be using kernel-next)
[01:04:53] <sivachandra> JoshTriplett: Ah, ok. Let me try this script.
[01:05:53] <sivachandra> JoshTriplett: I am building for x86-generic. how can I ensure it uses kernel-next?
[01:07:10] <JoshTriplett> sivachandra: Pass --profile=kernel-next to setup_board.
[01:08:25] <sivachandra> ok
[01:09:11] <sivachandra> JoshTriplett: let me go through all this and report back. thank yo
