Packages are installed under /sys/packages or /sys/apps.
Examples:
/sys/packages/package.example.com
/sys/apps/package.example.com [DEPRECATED].
Packages may be mounted directly in the package file package.example.com or under package.example.com/src [DEPRECATED].
In the latter case, intermediary file's are created under package.example.com to extend their type chains and make them centrally configurable.
