kernel parameter quiet

[jwinarske]

Is there an easy way to append quiet to the kernel parameters? Will this work?

KERNEL_ARGS_append = " quiet"

Basically this should work. Note that more recent yocto branches (honister and master) have a new override syntax, so KERNEL_ARGS:append = " quiet" would be appropriate in that case. You can do this in your local.conf or in a custom machine conf.

Also, here's a trick to make this conditional based on the image debug-tweaks setting, so you can make local debug builds that disable this, and have "production builds" be quiet:

KERNEL_ARGS:append = " ${@bb.utils.contains('IMAGE_FEATURES', 'debug-tweaks', '', 'quiet',d)}"

I like this approach. It might be good to have this as standard. Thanks!
