#####Temporarily linking /bin/sh to /tools/bin/bash
`ln /tools/bin/bash /bin/sh`
#####Creating temporary links linking to /tools/bin/bash
In order the for pre and post-installation scripts that come inside a standard .deb file to work, these need to be able to have access to a shell. These typically either specify using `/bin/sh` or `/bin/bash`. Without access to a shell at the exact location that the script specifies, the installation script will fail thus causing the installation of the package itself to fail.
We must mitigate this problem by making sure that the `/bin` directory already exists, and then creating symlinks from these two locations towards the bash we have in our temporary `/tools` environment.
When we get to the point of installing debian's "priority:essential" packages, which include both of these shells, these symlinks will be overwritten with native copies of these binaries.
