Thanks, Axel and Holger.

So the situation is:

I've uploaded -2 in order to
- see what the buildds say
- get more diagnostics
- get a .buildinfo file

And the result is:
- it built on my laptop and on the buildd
- we should have a .buildinfo file :)
- it still fails on the reproducible build servers
- and the diagnostics there failed as well (fixed in git, I got the
  order wrong)

Taking a step back: What the very simple module does is to try and
guess the FQDN of a machine, with various methods. And it seems this
doesn't always work (cf. "hostname: Temporary failure in name
resolution" in the logs of the failures but all other methods
which are tried later apparently fail as well).

So I guess we can say
- that the module and the tests probably work in most "real"
  situations
- but it can fail under "special" circumstances, which the RB hosts
  and Holger's build machine triggered (but nothing else or before,
  like Lucas' archive rebuilds).

We can now
- say "good enough" and forget about the issue
- or reopen the bug and lower the severity (and retitle it to
  something like "Sys::Hostname::Long fails if there is not
  networking/no DNS/something").
  
I'm not sure if/how the bug can be fixed, or if a failing `hostname'
is ultimately a bug in the package or in the environment.

Hm, and after writing this mail, I think that an environment where
`hostname' fails is maybe really to special in order to re-open the
bug.

But I'd still like to hear other opinions, that's why I started this
mail in the first place even if the bug is already closed :)


Cheers,
gregor
