Re: [fuse-devel] Overlay fs: what to do with inodes?

[Stef B. <st...@gm...>]

Fuse unionfs? Why? My module can do something special with symbolic
links (to directories), and can make them look like a directory,
fooling the user and the system.
This way I can make it look like local resources like an mounted usb
device is also mounted by this fuse module, and the same for network
resources Samba/Windows shares , mounted by the automounter, but
"mirrored" by this module. I do not know any unionfs which does that.

OK, correct me when I'm wrong, every fs mounted has it's own numbers,
and a number can appear more than once when comparing two fs's.

That explains a lot. I do not have to use the option use_ino then to
make things consistent.
