[Buildroot] Problem generating rootfs for ci20 defconfig

[Paulo Matos]

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:

>>>   Executing post-image script support/scripts/genimage.sh

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,

Paulo Matos

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?

 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.
