When building, $HOME is set to a non-existing dir. Previously it was always set to `/homeless-shelter`. After a build, the builder verifies that it doesn't exist. In some scenarios (specifically when using the linux sandbox with a single-user installation), it is possible to create the `/homeless-shelter` directory, and some tools will create it, resulting in a build error.
When building, $HOME is set to a non-existing directory. Previously it was always set to `/homeless-shelter`. Before a build, Nix verifies that it doesn't exist. In some scenarios (specifically when using the Linux sandbox with a single-user installation), it is possible to create the `/homeless-shelter` directory, and some tools will create it, resulting in a build error.
Now, on Linux, $HOME is set to `/proc/homeless-shelter`. This directory can never be created, since `/proc` is a virtual filesystem. This resolves the issue.
