avoid windows %APPDATA% in packer post-process

[Michael Cook]

Hi,

These days I treat my windows host as 'firmware' - and as a consequence I try to contain my windows C: drive as small as possible. The packer post-processor (this is for vagrant, probably same for others) seems to insist on using my %APPDATA%\... as a temporary holding location for intermediate files during creation of the vagrant 'box' - however there's never going to be space there for vmdks, and hence fails through lack of disk space. How can I tell post-processor to use a different location?

I'm guessing these lines in post-processor.go tell me it's not going to be possible...

// Create a temporary directory for us to build the contents of the box in
dir, err := ioutil.TempDir("", "packer")

the (brief) go doc indicates TempDirs are set for the os.

Guess something like this should work:

Go just ask the OS for the temp path.
