Because the Home Assistant user's home directory is on `/var`, Python
packages installed in the "user site" do not get the correct SELinux
labels and thus run in the wrong domain. This causes a lot of AVC
denials and other issues that prevent Home Assistant from working
correctly.
To resolve this issue, Home Assistant is now installed in a virtual
environment at `/usr/local/homeassistant`. This directory is still
owned by the Home Assistant user, allowing Home Assistant to manage
packages installed there. Since it is rooted under `/usr`, files are
labelled correctly and processes launched from executables there will
run in the correct domain.
