[Users] Debian - Odd, hopefully minor, machine name / prompt issue

[Ola Lundqvist]

Hi Jim

That depends on what you have on the system. In some cases the configuration
is dependent on the hostname. For example exim can get a bit confused if the
hostname is not the correct one.

I will start to look on this bug asap. As Kir said something must have
become wrong when the patchset was merged to Debian.

Best regards,

// Ola
