umount -a errors

[Sean Richards]

Hi,

Have build a system using Busybox 1.2 and a 2.6.17.1 kernel. On halt or 
reboot busybox umount gives an error saying 'unmount: Couldn't umount 
/:No such file or directory'. I have included below as much information 
as I think is relative. Any more information needed please let me know.

Cheers, Sean
