This integration will 8 take place automatically. 9 10 A rootfs.cpio file will be generated in the images/ directory. 11 This is the archive that will be included in the kernel image. 12 The default rootfs compression set in the kernel configuration 13 is used, regardless of how buildroot's cpio archive is 14 configured. 15 16 Note that enabling initramfs together with another filesystem 17 formats doesn't make sense: you would end up having two 18 identical root filesystems, one embedded inside the kernel 19 image, and one separately. 20 21comment "initramfs needs a Linux kernel to be built" 22 depends on !BR2_LINUX_KERNEL 23
