[HACKSSIGN]
Simplify the hackssign application usage.
You don't need anymore to specify which VM type you use. The client will attempt to
discover it by looking at available shared folders providers.
If it recognizes one, it will perform the assignation.
No Guest Additions/Tools installed will make the tool refuse to assign a drive letter
(obviously).
So basically, you just need to issue some: hackssign assign z ReactOS (for example)
