 mach and the build system store shared state in a common directory on the

 filesystem. The following directory will be created:

   {userdir}

 If you would like to use a different directory, hit CTRL+c and set the

 MOZBUILD_STATE_PATH environment variable to the directory you would like to

 use and re-run mach. For this change to take effect forever, you'll likely

 want to export this environment variable from your shell's init scripts.
