Hostname incorrect?

Support
1

/etc/hosts

127.0.0.1       localhost
::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

Running hostname reveals that the hostname is actually localhost.localdomain

Without correcting /etc/hosts the following error occurs with any command that is executed in terminal:
unable to resolve host

After updating /etc/hosts everything runs normally again.

127.0.0.1       localhost.localdomain
::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

Is this a random error or could there be a deeper reason?

Due to legacy (this forum didn’t exist yet) this was already reported in the other forums. More information there.
