While trying to generate an image using the ci20_defconfig (on git 84d471a0b1) with a few
extra libraries added I am getting the following error:

Does anybody understand what this part rootfs size refers to? The rootfs.ext4 size if the 128M I set as BR2_TARGET_ROOTFS_EXT2_SIZE but unsure what the other number is, or what it means.

Kind regards,

It comes from "size = 60M" in board/ci20/genimage.cfg.

Perhaps we should drop the size parameter for rootts in board/*/genimage.cfg and let genimage always use the size of the filesystem image.

Thomas, Yann, Arnout, what do you think?

Perhaps we should drop the size parameter for rootts in board/*/genimage.cfg and let genimage always use the size of the filesystem image.

That's the case for most genimage.cfg files anyway. I think the few which do
have a specified size are just historical accident.

Indeed. For the use case of wanting extra space to add more files are runtime to a writable file system, it makes more sense to set BR2_TARGET_ROOTFS_EXT2_SIZE (or similar) to something like 512MB rather than hardcoding the rootfs partition size to 512MB.

I was thinking the same. I sent a patch for ci20, but it indeed probably makes sense to do it for all defconfigs.
