Hi,
if you select gzip compression for the rootfs.cpio file
(BR2_TARGET_ROOTFS_CPIO_GZIP), then the rebuild of the kernel with
initramfs is going to fail:

I guess the fix for this is to change fs/initramfs/Config.in to select
BR2_TARGET_ROOTFS_CPIO_NONE, right ?

Yes, I guess so.

Odd, that's not what I'm seeing here.
in fs/common.mk the compression stuff is handled by creating the
compressed variant IN ADDITION to the uncompressed file, E.G.:
gzip -9 -c /home/peko/source/buildroot/test/images/rootfs.cpio > \
/home/peko/source/buildroot/test/images/rootfs.cpio.gz
So output/images/rootfs.cpio still exists when the kernel is rebuilt.
