Please help me test aufs

[T o n g <mlist4suntong@yahoo.com>]

Hi,

The aufs is supposed to be able to unify several directories and 
provide a merged single directory. but I found it doesn't work for me any 
more. 

If you have aufs enabled in your system, please help me test the 
following command and post back your result:

mkdir /tmp/rw /tmp/aufs
mount -t aufs -o br=/tmp/rw:${HOME} none /tmp/aufs
mount -o remount,append:${HOME} /tmp/aufs

The command is taken from "4. Usage" section from 
http://aufs.sourceforge.net/

Here is my error log: 

% mount -t aufs -o br=/tmp/rw:${HOME} none /tmp/aufs
/sbin/mount.aufs:plink.c:223: AUFS_CTL_PLINK_MAINT: Inappropriate ioctl 
for device

% mount -o remount,append:${HOME} /tmp/aufs
mount: can't find /tmp/aufs in /etc/fstab or /etc/mtab

I suspect that the error might be specific with my aufs build/distro. 
Mine is:

 aufs-modules-2.6.28-grml64_0+20090302-2+grml.03
 aufs-tools_20100601-1

Please help. 

Thanks
