- Skip systemd-resolved initialization on Android (ChromeOS crash fix) - Skip system DNS discovery commands on iOS mobile (sandbox restrictions) - Skip route-based DNS discovery on Android - Skip systemd resolver on Android - Add mobile platform checks to prevent sandbox access violations These changes ensure ctrld works correctly in mobile sandboxed environments where system commands and file access are restricted.
