Why delete this file? Shouldn't there still be a buildroot config?

I manually created a rootfs for each of the driver VMs because most of the files remain unused by the VM. So buildroot shouldn't be required for driver VMs.
The block driver VM contains:
/dev/sys/modules: Only contains kernel modules required by the block driver./init: This gets added during the build process usingpackrootfs
The sound driver VM contains:
/dev/sys/modules: Only contains kernel modules required by the block driver./init: This gets added during the build process usingpackrootfs/alsa: config files for alsa/alsactl/etc

If the file is missing you need to provide instructions for recreating the root FS, and in particular if there are any GPLd binaries in there how to get the source for them and rebuild them.

@wom-bat I have updated the readme for the 2 examples (sound driver readme, block driver readme). I just remembered that the sound driver VM requires a buildroot_config for building a statically linked alsactl. I've included the steps for reproducing this in the sound driver readme.

Could you summarise what you modified in the Linux kernels? What configuration options did you disable? |
