Description: 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). A lot of
software relies on that the local host name is resolvable via DNS to an IPv4 or
IPv6 address. When using dynamic hostnames this is usually achieved by patching
/etc/hosts which however is suboptimal since it requires a writable /etc file
system and is fragile because the file might also be edited by the
administrator. nss-myhostname simply returns 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/hostname is
thus no longer necessary.

---

When we make the system host name a bit more more dynamic this should allow us
to still guarantee that the hostname stays resolvable under all circumstances
without having to rewrite /etc/hosts all the time.
