cpio/initramfs: clarify their use in the help text Recent mails on the list show that it is not very clear how to create an initial RAM fs with buildroot. So make this more explicit in the cpio and initramfs help texts. Hopefully this will reduce the /init debugging we have to do.

Build a cpio archive of the root filesystem. This is typically
used for an initial RAM filesystem that is passed to the
kernel by the bootloader.

rootfs-cpio: add U-Boot image support Adds U-Boot image support for cpio root filesystems. This allows you to use the bootm command in U-Boot to load the rootfs. It makes it possible to verify the CRC of the initramfs before booting the kernel.

This can be useful to create a recovery system, for instance.

fs/cpio: allow users to provide their own dracut modules Dracut modules can only be looked for in HOST_DIR/lib/dracut/modules.d/ as dracut does not offer the possibility to look elsewhere. Installing files in HOST_DIR/ can do done either from a host-package, or via a post-built script; there is no overlay like there is for target/. This is a bit cumbersome. Additional modules are most probably developped in a relatively tight loop with the configuration files, so it makes sense to expose both close together. Add an option to the fs/cpio filesystem, so users can point to a list of modules to install. Signed-off-by: Yann E.

fs/cpio: accept a list of dracut.conf files It is not unusual that projects can target multiple boards, and in such cases, a lot is shared between boards and only the low-level stuff differ. Allow users to specify more than one dracut config file to cover tose cases. dracut does not accept more than one config file with the -c option, but it can load more than one from a directory with --confdir. So, we copy all the config files to a temporary directory and se that as --confdir. However, we can't drop passing -c, or dracut would read the system-wide /etc/dracut.conf (not sure if ${prefix} is even used), which we do not want. So, we use an empty file as -c; /dev/null comes in handy as an empty file. Signed-off-by: Yann E.
