If any step fails due to a download error, just rerun it.
|
||||
If you wish to customize the kernel or another package, include it (e.g. `linux-kernel`) in `COMPONENTS` to actually include that package on the image.
|
||||
You may also need to either adjust `qubes-src/installer-qubes-os/conf/comps-qubes.xml` (kernel -> kernel-latest), or build the package as "kernel" not "kernel-latest" (edit `suffix` file in the linux-kernel sources).
|

Make sure `audit=0` is not present in kernelopts / `/proc/cmdline`.
