Both options were introduced in systemd v243[1]. Those options can be
used to ensure that LinkLocalAddressing is only configured for a given
interface if DHCPv4 fails. To quote `systemd.network(5)`:
```
If "fallback" or "ipv4-fallback" is specified, then an IPv4
link-local address is configured only when DHCPv4 fails. If "fallback", an IPv6 link-local
address is always configured, and if "ipv4-fallback", the address is not configured. Note
that, the fallback mechanism works only when DHCPv4 client is enabled, that is, it requires
"DHCP=yes" or "DHCP=ipv4".
```

Fixes #71296 (Po4a build get stuck in a loop)
Term::ReadKey is an optional dependency. From upstream:
> This module is used to retrieve the terminal's line width.
> If it is not present, the line width can be specified with the COLUMN environment variable.
libusb1 can't depend on systemd in order to be compiling with musl,
because systemd can't be built with musl.
Since systemd provides udev, udev support needs to be disabled when
building libusb1.
Default behavior is to continue executing the script even when one or
multiple steps fail. We want to abort early if any part of the
initialization fails to not run with a partially initialized state.
Default behavior also allows dereferencing non-existent variables,
potentially resulting in hard-to-find bugs.
- gitlab-shell no longer requires ruby for anything else than the
install script, so the bundlerEnv stuff could be dropped
- gitlab-shell and gitlab-workhorse now report their versions
correctly
Previously it was missing a runtime dependency on setuptools:
[kier@saelli:~/checkouts/nixpkgs]$ $(nix-build -A python27Packages.pylint --no-out-link)/bin/pylint
Traceback (most recent call last):

With this change, the same command now correctly prints pylint's help text.
This only applies to Python 2.
