From 0137fbd74bff2ca3273da3725eb27d2262e3973d Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Sat, 6 Jul 2024 13:40:40 +0200 Subject: [PATCH] kernel: skip rebuilding kernel with ROOTFS_INITRAMFS_SEPARATE With PER_DEVICE_ROOTFS, rebuilding kernel is needed to embed the cpio image in the kernel image. With ROOTFS_INITRAMFS_SEPARATE, the cpio image is external hence we can reuse the same kernel image without rebuilding it.
