[Buildroot] [PATCH v2 1/2] configs/odroidc2: increase rootfs size to 124M

[Yann E. MORIN]

Dagg,

On 2021-09-11 19:25 +0300, Dagg Stompler spake thusly:
> as result of e2fsprogs version bump, the image size required was
> increased.
> so to fix it and make sure there is enough size, set BR2_TARGET_ROOTFS_EXT2_SIZE
> to 124M

So, I was wondering what the reason for the size increase was, so I
spawned a build in three conditions:

  - my server's Ubuntu 16.04
  - my laptop's Ubuntu 21.04
  - a docker Bullseye on my server (so, minus the kernel, a stock Debian
    Bullseye)

In all three cases, the build succeeded with current master. The sice
of the target/ directory is roughly 40MiB in all three cases, which is
still far enoiugh from 60MiB that it should not cause any issue.

So, I'm still not sure that the reason is "Debian Bullseye", or that the
solution is "increase the filesystem size".

Could you please try by aplying this patch to master, and rerun the
build, and share the error message, please:

If only this patch is applied, then the build *will* fail, becasue the
size in genimage.cfg is still not fixed. Both sizes must be changed in
the same patch.
