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

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 =)
