Windows 2000 Junction Points
Thu Dec 6 07:56:00 GMT 2001
Windows 2000 (having NTFS 5.0) allows the creation of directory
symbolic links. This can be used as mount points for hard drive
volumes or to symlink directories across file systems. In the
literature, the directory links are called "junction points".
Disk Administration snap-in can be used to mount a drive to a
directory or you can use linkd.exe (ResKit) or junction.exe
This is the closest thing I can find to simulate:
ln -s /source /destination
Now here's my question:
When you perform a directory symlink in cygwin, you end up with a
.LNK file even though you can cd into the link.
$ ln -s /cygdrive/c /mnt/test
$ ls -l
dr-xr-xr-x 6 Administ Administ 0 Dec 6 09:47 ./
dr-xr-xr-x 12 Administ Administ 4096 Nov 28 12:48 ../
dr-xr-xr-x 12 Administ Administ 8192 Dec 6 09:47 c/
dr-xr-xr-x 3 Administ Administ 4096 Dec 3 12:48 d/
dr-xr-xr-x 5 Administ Administ 4096 Dec 3 12:48 e/
drwxr-xr-x 1 vciadmin Administ 0 Dec 4 08:35 h/
lrwxrwxrwx 1 vciadmin Administ 94 Dec 6 09:47 test -> /cygdrive/c/
$ cd test
This works as expected. However, from outside cygwin:
Volume in drive G is DATA
Volume Serial Number is 98D5-B7E1
Directory of G:\cygwin\mnt
12/06/2001 09:47a <DIR> .
12/06/2001 09:47a <DIR> ..
11/28/2001 11:26a <JUNCTION> c
11/28/2001 11:26a <JUNCTION> d
11/28/2001 11:27a <JUNCTION> e
12/04/2001 08:34a <JUNCTION> h
12/06/2001 09:47a 94 test.lnk
So the effect is lost.
Because hard links work in cygwin as expected, is it far fetched
for ln -s <directory> <linkname> to create actual junction points
instead of .LNK files?
If I'm way off base here, please feel free to let me know :)
