Implementation Translations: Translations are registered dynamically. socket(AF_INET, SOCK_RAW, IPPROTO_ICMP) translates to native-socket: sockdom: AF_INET, socktype: SOCK_RAW Translations aim to be invariant: kill(32323, SIGHUP) translates to native-kill: pidname: /usr/local/bin/identify, signame: SIGHUP Argument normalization prevents symbolic link races. Normalized arguments replace the original arguments. The kernel does not follow symbolic links for normalized arguments.
