bootloader = "0.9"

**Note:** This post is only compatible with `bootloader v0.9`. Newer versions use a different build system and will result in build errors when following this post.

Adding the bootloader as a dependency is not enough to actually create a bootable disk image. The problem is that we need to link our kernel with the bootloader after compilation, but cargo has no support for [post-build scripts].
