Pull request overview
This PR adds support for running bolt applications without a read-write overlay layer, providing a more restrictive filesystem environment where only a designated home directory is writable. The changes introduce a new command-line option --rw-overlay that allows users to enable or disable the overlay layer.
Key changes:
- Added
--rw-overlay=<true/false>option to control whether apps run with a full read-write overlay or with only a writable home directory - Moved HOME environment variable from static template to dynamic configuration, changing from
/home/rootto/home - Implemented conditional directory setup and mounting based on the rwOverlay option
