More desktop use of Linux more cases of ntfs and fat mounted under

percent normal for most Ubuntu users so there are a lot of them out
there doing it. I am future looking there are other filesystems
coming with there own issues as well.
Same issue with samba no common store for extra permissions exist so
on file systems that don't support there permissions storage it goes
back into there tdb storage.
Basically scanning everything to detect issues currently nicely
complex. We have a huge permissions mess. Some permissions are
processed by the file system drivers. Some are processed by vfs then
others processed and stored by individual applications. So no where
in Linux can you see all the permissions being applied to a single
file to be sure there is not a secuirty risk somewhere. Samba or
equal allowing access to remove a virus signature from the black list
or added something that should not be allowed to the white list would
be major problems.
Posix has not helped US here at all. No where in posix does it
provide anything to clean up this mess. Does solarias have a solution
I know BSD and Linux does not. I think all posix OS's have a mess in
this section.
