Worked on the coolsnowwolf/immortalwrt repository to optimize the feed update process by implementing shallow cloning for both main feeds and their submodules. This approach reduced bandwidth consumption and disk usage, resulting in faster and more reliable update cycles. The solution involved scripting in Shell and leveraging advanced Git techniques to ensure that only the necessary commit data was retrieved during updates. By maintaining cross-module consistency and focusing on script-level optimization, the work improved repository maintenance and operational efficiency. No major bugs were addressed during this period, with efforts concentrated on delivering this efficiency-focused feature using Git and scripting skills.
