Worked on the lima-vm/lima repository to implement automatic disk unlock on startup for instance-bound disks, addressing reliability issues after unclean shutdowns. Refactored the disk unlock logic by extracting it into a shared Disk.LockForInstance() method, enabling both VZ and QEMU drivers to reuse the code and reducing duplication. This approach resolved startup failures where disks were incorrectly reported as in use by the same instance during attach, eliminating a common boot-time blocker. Focused on backend development using Go, with an emphasis on cross-driver disk management, the work improved startup reliability, reduced boot-time errors, and enhanced code maintainability for future enhancements.
