file permission problem.

I have done some experiment with fusexmp and I think the
permissions are
weird. I'd appreciate it if someone can answer the following
questions.

 

1.	If I start fusexmp as root without allow_other option,  I
cannot
access the mount point running as non-root user. Is this
expected behavior?
If is , I guess it's ok.

 

2.	As root,  start fuse with allow_other option,, now I can
create file
as non-root user. But user/group of the file show as
"root, root", should
they be the specific user? But I can delete the file owned
by root as a
non-root user. (?? Is this correct or expected?)

 

3.	As root, start fuse with allow_other,default_permissions
options, if
I do a touch "testfile" under fuse mount  point,
the file is created, but I
got errors: "Set time failed, permission denied"
(exact message may differ).
The file owner is still root. I would expect the file owner
to be the
specific user who created the file. I don't think this
follows the file
system convention?

 

Now, my question is: how do I mount a fuse file system
accessible by a
non-root user but when that user creates files,
"ls" will show that user as
the owner?

 

 

Thanks

 

Brian

The fusexmp example doesn't have any code to change the
ownership or
permissions of files, if you want this behaviour, you need
to explicitly
code it yourself.
