Comment (by Roland Haas):

It’s a failed attempt at a fix. I may be adaptable though I am not really sure. The problem is that, as written, it also sets basedir which should not be done. The pull request would have duplicated the created default section as a section for the current machine, which is too much. Basically there are only some options that one wants to overwrite (one must overwrite since the options exist in the machine entry, obvious for basedir but also, annoyingly, for things like allocation which is set to NO_ALLOCATION for most machines that do require an allocation).
