+<longdescription lang="en">
+nss-myhostname is a plugin for the GNU Name Service Switch (NSS) functionality
+of the GNU C Library (glibc) providing host name resolution for the locally
+configured system hostname as returned by gethostname(2). Various software
+relies on an always resolvable local host name. When using dynamic hostnames
+this is usually achieved by patching /etc/hosts at the same time as changing
+the host name. This however is not ideal since it requires a writable /etc
+file system and is fragile because the file might be edited by the
+administrator at the same time. nss-myhostname simply returns all locally
+configure public IP addresses, or -- if none are configured -- the IPv4
+address 127.0.0.2 (wich is on the local loopback) and the IPv6 address ::1
+(which is the local host) for whatever system hostname is configured locally.
+Patching /etc/hosts is thus no longer necessary.
