I agree with you. I did not think of this since I think there IS
compatibility code in minix.xfs. But I agree it should be removed from
there and factorized in the kernel.

Then you should have wrote code to prevent access from TOS domain. ;-)

Did you read my mail ? The problem is already present since there can
already be 2 (ore more) files with the same name ("foobarfoo.bar" and
"foobarfoo2.bar" both appear as "foobarfo.bar"). A solution is to make
FOO.BAR out of reach in TOS domain.

Again I don't understand your reply. I did not wrote it was the way
minixfs reacted. Of course I know it's not ! I wrote it's the way it
_SHOULD_ always had reacted.

OK. You're right.

I think this imply removing compatibility code from minix.xfs to get a
constant response between minixfs and ext2fs.

Now that I think of this code as a kernel part, there could be a
MINT.CNF option to control this. A value to see only files with
lowercase 8.3 filenames from TOS domain app, another to see them all,
but then with possible duplicates. This could even be controled on a per
drive letter basis.

Something like "TOS_DUPLICATE_ALLOWED=C,F,U" (any other idea for the
name is welcome) would be fine I think.

Do you agree with this ?
