[Bug]: networking.interfaces tries macOS ipconfig(8) on non-macOS

[klemensn]

Is this a critical security issue?

• This is not a security issue.

Describe the Bug

There's no point in executing a command for which the program does not exist:

openfact/lib/facter/resolvers/networking.rb

Line 76 in 17bbb5b

result = Facter::Core::Execution.execute("ipconfig getoption #{interface_name} " \

It also seems odd that despite passing a single fact for a single interface, besaid command is still tried for all interfaces:

$ facter --debug networking.interfaces.iwx0 2>&1 | grep ipconfig
[2026-02-08 20:20:54.915390 ] DEBUG Facter::Core::Execution::Posix - Executing command: ipconfig getoption iwx0 server_identifier 
[2026-02-08 20:20:54.919833 ] DEBUG Facter::Core::Execution::Posix - Failed while executing 'ipconfig getoption iwx0 server_identifier': No such file or directory - ipconfig 
... repeats for every interface on the system ...

Expected Behavior

Do not try to execute platform specific programs known to not exist.

Steps to Reproduce

1. use networking.interfaces on non-macOS
2. observe execution failure in --debug logs, via ktrace(1) or the like

Environment

openfact 5.3.0 on OpenBSD 7.8-current.

Additional Context

No response

I'd add that "common" Networking resolver shouldn't call any command, as everything in this field is OS-specific. I see ifconfig -a call in interfaces_data() also. It was good enough 10 years ago, but these days modern Linux distros doesn't ship ifconfig by default anymore.. so it's *BSD/MacOS-only now.
