Worked on the google/android-cuttlefish repository to address device ownership initialization issues in host resource scripts. Focused on improving the reliability of virtualization environments by correcting the chown command syntax from user.group to user:group within shell scripts, ensuring proper ownership assignment for devices such as /dev/kvm, /dev/vhost-net, and /dev/vhost-vsock. This shell scripting update eliminated startup warnings and reduced operational risk in both CI and production settings. Leveraged expertise in Shell and Linux system administration to enhance script robustness, directly contributing to more stable device access and smoother initialization processes in virtualized host system environments.
