11:39:21 < uroboro> saurik: what's the purpose of Router Advisement Daemon?
11:41:00 < saurik> uroboro: the network-cmds package includes a tool that apple started shipping on iOS 8. users who installed the package and then uninstalled it would lose the tool. users who installed the package also would get a "different" tool. this new package structure was a hack I put together to 1) make new installs never overwrite the file on any device, 2) make uninstall-to-delete not possible, and 3) totally sidestep this on iOS 9
11:42:42 < uroboro> saurik: so its unneeded on iOS 7 and earlier?
11:46:09 < saurik> uroboro: on iOS 7 and earlier the package provides rtadvd, which used to be provided by the network-cmds package. so it depends on what you mean by "needed". if you upgrade to the latest version of network-cmds (which no longer includes rtadvd) it depends on the separate rtadvd package to provide the file (except on iOS 9, where the separate package will never install)
11:48:12 < uroboro> saurik: I'd guess that it is needed since network-cmds doesn't provide the tool anymore
