Contrary + to SIGHUP, this does not restart the DNS plugin and will not + interrupt name resolution. + + When NetworkManager is not managing DNS, the signal forces + a restart of operations that depend on the DNS + configuration (like the resolution of the system hostname + via reverse DNS, or the resolution of WireGuard peers); + therefore, it can be used to tell NetworkManager that the + content of resolv.conf was changed externally. + In the future, further actions may be added. A SIGUSR1 means to write out data like resolv.conf, or refresh a cache. It is a subset of what is done for SIGHUP without reloading |
