Can you enclose the binary & check with (), to clarify, what's going on here?

This needs error checkiing, getenv() might return NULL....

Please break this into two lines...

We try to avoid declaring variables and invoking functions in the same
line. Could you split this up into two?
It might be nicer to use strjoin() here, and just concatenate the full
thing in one step, and then use mkdir_parents() instead of mkdir_p() to
create the parent directory...
