Windows would have this same problem with NTFS on Linux. If I am under Linux and make
changes to
files and create files how does linux-NTFS assign the proper SID and such to the files?
This has
been a long time problem that NTFS has with taking a drive from one Windows box to
another. Its
the same situation and mostly pointless. 99% of new ReactOS are not going to care and the
resources we get from having a better filesystem now can be put in to developing a NTFS
replacement.

If the ext2fsd supported ext3 journals there would be nothing wrong with using it. I mean
hell
right now ReactOS does not have a security subsystem so this whole discussion is a moot
point.
Unless you feel like implementing lsass =)

Hi Steven. Did we had already contact with the guy who has written
this driver? http://www.fs-driver.org/author.html
Should I contact him or is 'our' driver the same or the italian one?

At least I think that every fs is better than fat. Independent of its 
missing features.

True.  The filesystem can corrupt itself under any operating system that
multitasks, and even some that are single user single tasking...
