in thread capturing command output

That's why I normally code a wrapper around system calls.
Like this?
sub backticks { `$_[0]`; }

    Almost. Although your backticks is a bit short on the logging and redirection part ;-)
      It's using the same logging as the OP did (that is, none). And I fail to see why backtick "$cmd 2>&1", using the same $cmd from the OP doesn't give you redirection.

        Although the original does no logging, I dared to propose that this might be useful for non-trivial calls. As might be a redirection duplication of stderr and/or stdout to some location where you can inspect it. Or show it depending on a verbosity option.
        And yes, all of this is unnecessary in perfect code.
