Sorry being late with the review. Recently some effort has been put to replace the "PATH_MAX/snprintf() combo" with code using strbuf. So I think for new developed code it could make sense to avoid PATH_MAX from the start. To my knowledge mkpathdup() from path.c can be used, (or are there better ways ?) and the whole function will look like below (not tested)
