In dired-create-files.

How do you compare two files with file-attributes?
Locally, equal is ok, but when using /sudo::.. the gid-change, inode
and device-num are differents:

/home/thierry/Test:

--8<---------------cut here---------------start------------->8---
(:type t :links 2 :uid "thierry" :gid "thierry" :access-time
       (20241 21214)
       :modif-time
       (20241 20731)
       :status
       (20241 20731)
       :size 4096 :mode "drwxrwxr-x" :gid-change nil 
       :inode 4598437 :device-num 2049)
--8<---------------cut here---------------end--------------->8---

/sudo::/home/thierry/Test

--8<---------------cut here---------------start------------->8---
(:type t :links 2 :uid "thierry" :gid "thierry" :access-time
       (20241 21214)
       :modif-time
       (20241 20731)
       :status
       (20241 20731)
       :size 4096 :mode "drwxrwxr-x" :gid-change t 
       :inode (70 . 10917)
       :device-num (-1 . 0))
--8<---------------cut here---------------end--------------->8---

On info we have:
`(5888 2 . 43978)'
      has an inode number of 6473924464520138.

`(15479 . 46724)'
      is on the file-system device whose number is 1014478468.

How do you get such results?

Thanks.
