here you can pass ignore_status=False, to match the structure of utils.run.

Here, just pass ignore_status value

this if can be reversed
if ignore_status:
return cmd_result.exit_status, cmd_result.stdout.strip()
else:
return cmd_result.stdout.strip()
To be honest, I'm not a huge fan of functions that return different
things depending on input, really. I'd return the tuple (exit status,
stdout) anyway in both cases, even it being 0, it's less of a surprise
for the API users.
