The reason to want a Windows appliance at all is twofold: (1) better

Could you please tell more technical details? We support NTFS attributes,
volume management, etc for years. Thanks.

For me, the principal driver is to use native software management tools,

Native on Linux or Windows?

We don't reimplement Windows NTFS tools on Linux (actually we were some
years ahead in some of them) but try to make NTFS features available via
common Linux interfaces.

Native on Windows. As far as we're concerned, Windows filesystem access from Linux is not a problem.

FWIW, we have only encountered one significant problem, which is that ntfs-3g is case sensitive, whereas Windows (but not ntfs itself) is not. The practical upshot of this is that if you read a path out of a configuration file on a Windows system and then attempt to use it, chances are it won't work because the case is wrong, which Windows doesn't care about. This requires a fairly disgusting hack for munging paths before use on Windows guests. If it were possible to supply a mount option to mount case-insensitive this would be a great help.

However, it's not going to help me install a new storage driver without reverse engineering Windows itself.

particular for driver installation. Native filesystem and volume management is
a bonus.

Out of curiosity, who's 'we'?
