mount(8) shows /etc/mtab file.
If the file didn't exist and you didn't install /sbin/mount.aufs, or you
used -n option to you mount(8), then you need to create /etc/mtab
manually.
I suggest you to execute this command just after mounting aufs.
# cp /proc/mounts /etc/mtab
Additionally, if you use 'mount -o remount,... /your/aufs' later, it is
recommended to install mount.aufs.
Current aufs produces all branch paths to /proc/mounts.
Therefore if you have a lot of branches, you may meet a limitation of a
page which is usually 4k bytes. mount(8), /etc/mtab, /proc/mounts have
this limitation.
I will try sysfs and modify aufs entry in /proc/mounts in a few weeks.
