We may call CopyFile() and thus GetFileInformationByHandle(), which retrieves the volume serial number, many times when setting up a prefix, before mountmgr has been initialized.

There might be a better way of deriving a serial from a UUID, but by my understanding, Linux uses version 4 UUIDs, and taking the last 4 bytes is as random as it can be. I don't know about Mac.
For folders such as drive_c which are not separate host systems, this returns a serial with the high byte containing the DOS drive letter, and the other three bytes zero, so it would seem to be exactly as unique and stable as the volume GUID itself.

Signed-off-by: Zebediah Figura zfigura@codeweavers.com --- This paves the way for an implementation of GetVolumeInformation() on top of ntdll. Unfortunately, I ran into a snag while doing so, which is that one of the tests attempts to open a file by a device path other than the DOS one (specifically, \?\Volume{...}). mountmgr allows that, which was enough for kernel32 to fall back to assuming NTFS. Unless we implement a similar fallback (which feels much like papering over the problem), that test would start failing.
I don't know how to resolve this. One way is to hook up the missing IRPs in mountmgr, but this seems like more work than its worth. It'd be nice for ntdll to be able to recognize volume paths such that they resolve to the same Unix file object as the equivalent DOS path, but there are many ways to achieve this goal and I can't even guess at what would be the right one.
