Yeah, I didn't like this aspect when this patch was originally
submitted. We want to keep the code legible for future new
contributors. Having these generic-sounding but specific-in-purpose
wrapper functions can be pretty confusing. Let's use mkdir() when it's
the appropriate function, and let's figure out a different name for
"make a data directory subdirectory in a secure and robust way".
