Initramfs support?

Initramfs support?

[Rob Kramer]

Hi,

I've been trying to figure out how/if OE supports creation of initramfs
files. There's initramfs-uniboot and friends in initrdscripts, but I'm not
sure if that is current or useful, as it doesn't seem to be used by
anything, anywhere.

Then there's linux-hackndev, which builds a mini-busybox on the fly. But
that seems a bit hackish..

Anyone know if there's a good way to have OE create an initramfs archive of
a bunch of files that I provide?

Cheers!

What I do:

- define a custom image or use something like minimal-image
- add cpio.gz to IMAGE_FSTYPES
- use the resulting cpio.gz as your initramfs

The following ramblings may or may not be useful:

Thanks, I guess that's the way to go. I was hoping I could modify my main
image (already custom) to also create a cpio.gz, but a second image may be
just as clean. The x270 images are a good reference..

Cheers!
