4Subject: [PATCH 3/4] Support for booting without initramfs
5
6Previously when initramfs-* was not found in a deployment's
7boot directory, it was assumed that rootfs is prepared for
8ostree booting by a kernel patch.
9
10With this patch, the behaviour changes to be - if initramfs-*
11is not found, assume that system is using a static
12ostree-prepare-root as init process. Booting without initramfs
13is a common use case on embedded systems. This approach is
14also more convenient, than having to patch the kernel.
