A major red flag I see is: you're messing with global machine state even
if you work with /usr/local.

I'd recommend that you avoid touching anything outside of the user
unless you really need to. The less persistent state you end up with
after testing a build, the less cruft will build up in the machine over

The last thing you want is stray files from a previous test or unrelated
test kicking in and tricking you. If you run your tests from a user, you
can trivially make another one or recreate it if you suspect you've
tainted it. With global state, you pretty much have to re-provision the
whole machine.
