b Batch mode. Optimized for huge recursive copies, but less secure if a crash happens during the copy.
```
It seems the "less secure if a crash happens" does not need a crash to
happen.
With batch mode:
```
/[...]/.
Start (0) does not point to parent (___)
```
For pretty much everything copied in.
Without batch mode, everything passes `fsck`.

This allows, finally, proper detection when postgresql is ready to
accept connections. Until now, it was possible that services depending
on postgresql would fail in a race condition trying to connect
to postgresql.
This fixes some quirks I introduced in previous commits.
1. No need for an extra newline when printing the output of shell commands.
2. 'or die' is what's already used in the NixOS test sources, while
'die unless' has no occurrences.
When reworking the rspamd workers I disallowed `proxy` as a type and
instead used `rspamd_proxy` which is the correct name for that worker
type. That change breaks peoples existing config and so I have made this
commit which allows `proxy` as a worker type again but makes it behave
as `rspamd_proxy` and prints a warning if you use it.
This commit adds an assertion that checks that either `configFile` or
`configuration` is configured for alertmanager. The alertmanager config
can not be an empty attributeset. The check executed with `amtool` fails
before the service even has the chance to start. We should probably not
allow a broken alertmanager configuration anyway.
This also introduces a test for alertmanager configuration that piggy
backs on the existing prometheus tests.
The nixos test is a bit misleading, as the given nginx configuration
would always cause gitlab to redirect to localhost, which is clearly not
what you want in a production setup.
Instead we now enable services.nginx.recommendedProxySettings,
curl against http://gitlab, and assure we get redirected to that same
hostname, too.
Previously I got the following error message:
```
error: opening file '/home/ma27/Projects/nixpkgs/nixos/modules/installer/default.nix': No such file or directory
```
Probably related to 6c68fbd4e1.
Mininet (https://github.com/mininet/mininet) is a popular network emulator that
glues several components such as network namespaces, traffic control
commands into a set of python bindings. It is then "easy" to describe a
topology and run experiments on it.
