Normally the environment is much smaller, so I wouldn't expect issues
here. The alternative to making the environment smaller would be to move
other partitions to the back. This would probably hurt more, especially
since a regular fdisk starts the first partition at offset 1MiB.

Another approach would be to use a MBR partition for the environment
instead of using the raw device.

We can't increase the barebox partition without shrinking the
environment right behind it. Or do you mean that we first shrink
the environment and in a second patch increase the barebox partition?
