initrdscripts: add install scripts with a second rootfs
These are meant to be used by a master image, for a simple initial setup. The install scripts are similar to the default ones, but: - custom partitioning, replaces the swap partiton with a second root filesystem - adds labels to the partitions - preconfigures a boot loader entry for the second rootfs Part of [YOCTO #5614] (From OE-Core rev: 39fcab00cd3b85d40966689e31b4c7748f630739) Signed-off-by: Stefan Stanacar <stefanx.stanacar@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
