Here's a very obvious, trivial example: wherever I am I can now simply type "ping gateway" to know whether connectivity to my local router works. I also know that in my local wlan, as well as in the one of my girlfriend's or my parent's: I can reconfigure the router by typing http://gateway/ into my webbrowser, without having to check IP configuration, leave the web browser, or even know the router's brand or default configuration. > As I tried to explain above, I'm not really worried about nss_myhostname > overriding name resolution, but that software relies on the specific > functionality of the “gateway” name provided by nss_myhostname, but > *this* name is overridden by DNS (with a suitable search path) or > nss_files, so that it no longer resolves to the expected address. Search lists are local configuration. Software which relies on specific search paths to be configured will already break pretty much everywhere...
