helloworld image

helloworld image

[Leon Woestenberg]

Hello (world),


when compiling my favorite minimal image ("helloworld-image") under
both the minimal-distro and angstrom
shows 4 MB of cruft being dragged in.

What happened?

I would like to start with nothing and then configure the system for
what I need.

Should I start another more-minimal distro or can we change the
minimal distro to be truely minimalistic?


# Hello world image
# Contains *only* a statically linked hello world init program

IMAGE_INSTALL = "helloworld"
IMAGE_LINGUAS = ""

inherit image


Regards,

It might be worth trying DISTRO=micro to see if that works any better
for you.

Thanks for the suggestion.

Instead I would like to learn how is (wrongly) determined what goes
into the image.

This looks pretty definite to me, nothing should override the image
recipe on this one:

IMAGE_INSTALL = "helloworld"

You're confusing image and distro again. With angstrom I'm using a 80KiB
big image that has an fbdev based gui, so it looks your image recipe is
doing something wrong.

I think I am not confusing them again, I think other people are.

This is what happened:

Changes to the distro have made the image bigger (80 kB to 4MB).

Apparently, the image does not define what goes in the image, but the
distro now specifies a minimum amount of packages that goes in.

Also, we seem to be moving to the point where people must both disable
default packages to go in, and enable packages to go in.

Why not simply go back to the idea where the images defines what goes
in?  I think it's more user friendly.

Actually it does not, your image recipe has the final say. Like I said,
I have no trouble building an 80KiB image with angstrom.

I'd like to know what steps you take to make such an image.

Perhaps you could share your config files so that others can
see how it's done (as opposed to just repeating that it *can*
be done)?

the local.conf I use is the same as contrib/angstrom/local.conf, the
image is in recipes/kexecboot/initramfs-kexecboot-image.bb.
