mergerfs version: 2.24.2

As the docs say:

Please make sure you are using the latest release or have tried it in comparison. Old versions, which are often included in distros like Debian and Ubuntu, are not ever going to be updated and your bug may have been addressed already.

2.24.2 was released in early 2018. Please use a current version of the software.
