Share username and hostname amongst all anonymity distributions
_Originally created by Tails on [#5655 (Redmine)](https://public-redmine-archive.tails.boum.org/code/issues/5655)_
As suggested by adrelanos on [Tails-dev - Let’s share username,
/etc/hostname and /etc/host among all anonymity
distributions](https://mailman.boum.org/pipermail/tails-dev/2013-January/002457.html)
- username: user
- /etc/hostname: host
- /etc/hosts: 127.0.0.1 host.localdomain host
No convincing reason not to do this [was
provided](https://mailman.boum.org/pipermail/tails-dev/2013-April/002830.html),
so we decided to do it.
