  15 description
  16         nss-myhostname is a plugin for the GNU Name Service Switch (NSS)
  17         functionality of the GNU C Library (glibc) providing host name
  18         resolution for the locally configured system hostname as returned by
  19         gethostname(2). Various software relies on an always resolvable local
  20         host name. When using dynamic hostnames this is usually achieved by
  21         patching /etc/hosts at the same time as changing the host name. This
  22         however is not ideal since it requires a writable /etc file system and
  23         is fragile because the file might be edited by the administrator at
  24         the same time. nss-myhostname simply returns all locally configure
  25         public IP addresses, or -- if none are configured -- the IPv4 address
  26         127.0.0.2 (wich is on the local loopback) and the IPv6 address ::1
  27         (which is the local host) for whatever system hostname is configured
  28         locally. Patching /etc/hosts is thus no longer necessary.
