Worked on the rackerlabs/genestack repository to deliver a configurable Lab Network MTU feature within the hyperconverged lab script. Focused on DevOps and networking, the work replaced a previously hard-coded MTU value of 1500 with a tunable LAB_NETWORK_MTU environment variable, allowing users to adjust network settings for tenant networks as needed. This change, implemented using shell scripting, ensures consistent and adaptable lab networking performance across different environments. The update was linked to a specific commit for traceability and addressed issue #1224. No major bugs were fixed during this period, as the primary effort centered on feature development and scalability.
