mhddfs mount in /etc/fstab fails if periodic fsck kicks in how to solve ?

( ubuntu oneiric 11.10 server)

Here is my /etc/fstab

# /etc/fstab: static file system information.
proc /proc proc nodev,noexec,nosuid 0 0

---------------------

If the periodic fsck run starts during boot, my mhddfs mount fails and the server waits for a ctrl+d to continue boot...

How can I prevent the "hang" while keeping my periodic fsck runs ?

Is is possible for mountall to wait the end of the fsck before continuing mountin file systems ?
