Solaris 10 SPARCS same ino number for file system

Thank you all for replying. I understand the link to directories has the same inode number, and yes,if it is a different file system, it may have the same inode number also. But here is what I found out from Solaris 10 (SPARCS) file system . Below you would find that /usr, /usr/bin, /var/sadm all of them have the same inode nubmer 4, and they are under the same file system and no links between them...Could someone help to explain why the inode number is not unique? Thanks a lot.

NTFSCP(8)						      System Manager's Manual							 NTFSCP(8)

NAME
ntfscp - overwrite file on an NTFS volume. SYNOPSIS
ntfscp [options] device source_file destination DESCRIPTION
ntfscp will overwrite file on an NTFS volume. At present ntfscp can't create new files. destination can be either file or directory. In case if destination is directory specified by name then source_file is copied into this directory, in case if destination is directory and specified by inode number then unnamed data attribute is created for this inode and source_file is copied into it (WARNING: it's unusual to have unnamed data streams in the directories, think twice before specifying directory by inode number). OPTIONS
Below is a summary of all the options that ntfscp accepts. Nearly all options have two equivalent names. The short name is preceded by - and the long name is preceded by --. Any single letter options, that don't take an argument, can be combined into a single command, e.g. -fv is equivalent to -f -v. Long named options can be abbreviated to any unique prefix of their name. -a, --attribute NUM Write to this attribute. -i, --inode Treat destination as inode number. -N, --attr-name NAME Write to attribute with this name. -n, --no-action Use this option to make a test run before doing the real copy operation. Volume will be opened read-only and no write will be done. -f, --force This will override some sensible defaults, such as not working with a mounted volume. Use this option with caution. -h, --help Show a list of options with a brief description of each one. -q, --quiet Suppress some debug/warning/error messages. -V, --version Show the version number, copyright and license ntfscp. -v, --verbose Display more debug/warning/error messages. DATA STREAMS
All data on NTFS is stored in streams, which can have names. A file can have more than one data streams, but exactly one must have no name. The size of a file is the size of its unnamed data stream. Usually when you don't specify stream name you are access to unnamed data stream. If you want access to named data stream you need to add ":stream_name" to the filename. For example: by opening "some.mp3:artist" you will open stream "artist" in "some.mp3". But windows usually prevent you from accessing to named data streams, so you need to use some program like FAR or utils from cygwin to access named data streams. EXAMPLES
Copy new_boot.ini from /home/user as boot.ini to the root of an /dev/hda1 NTFS volume: ntfscp /dev/hda1 /home/user/new_boot.ini boot.ini Copy myfile to C:somepathmyfile:stream (assume that /dev/hda1 letter in windows is C): ntfscp -N stream /dev/hda1 myfile /some/path BUGS
There are no known problems with ntfscp. If you find a bug please send an email describing the problem to the development team: linux-ntfs-dev@lists.sourceforge.net AUTHORS
