[Bug-tar] tar not setting permissions on a directory in a restore hierarchy when a filesystem is mounted on said directory

I've observed an odd behavior where gnu tar (on Linux) does not 
restore/change the permissions on a directory in the restore hierarchy 
when a filesystem is mounted on said directory.  However, if the same 
directory exists without a file system mounted on it, tar correctly 
sets the permissions.  Is this the expected behavior of gnu tar?

Thanks in advance,
Doug

Brief Details...

# cd /root/test_dir

# tar -x -p -v -v -f test-tar.tar
drwx------ root/root         0 2003-10-17 03:43:17 ./
drwxr-xr-t root/root         0 2003-10-17 03:43:17 ./fail/
drwxr-xr-t root/root         0 2003-10-17 03:43:17 ./pass/

# ls -la
total 3
drwx------    4 root     root           96 Oct 17 03:44 .
drwx------   22 root     root         1176 Oct 17 03:44 ..
drwx------    2 root     root           40 Oct 17 03:44 fail
drwxr-xr-t    2 root     root           48 Oct 17 03:44 pass

# df | grep tar
tmpfs                  1031608         0   1031608   0%
/root/test-tar/fail

This happens with reiser, tmpfs, ext2 as well as with different chmod
bits on the 'fail' directory in the archive.  I can post the script I
used to produce these results if necessary.
