I don't know where the entry points to the APIs in question are in user space, I'll leave that for someone else to address. I've replaced various libraries for different purposes many times and it can work depending on the library or application in question. 

That being said, if you want to bypass a file system driver, I don't think you want to try to use ReactOS ntfs implementation as a drop in replacement as of yet, at least not if you care about your data integrity. Even if the ReactOS team said they had a 100% functional implantation I'd be cautious using on volume with data I cared about.

Thanks

I somehow lost rights to folders in my start menu.  In the Windows GUI,
I become owner, but then get "access denied" when I try to give myself
full control.  This, and many other ACL (Access Control Lists, in NTFS)
annoyances I deal with, makes me desire to disable ACL altogether.

I have used SetACL successfully, but to be honest, ACL is not something
I want to learn or deal with.  It is only an annoyance along the way to
getting things done.  Many go up in arms over this because of "security"
concerns.  I have been without security for a very long time without
issues.  Perhaps I am lucky, but really, I don't have that much to lose
anyway.

I make unattended windows installations, and have thought to use a
modified library with the help of DSEO
http://www.ngohq.com/?page=dseo

Would the library be ntfs.sys?
