[CentOS] Force run of quotacheck at boot

Hi All,

I think I have managed to corrupt my quota files so I need to run 
`quotacheck` but that needs the partition to have quotas off or be 
unmounted which isn't ideal for a production system :-p

I was trying to find a way to force the system to do a full `quotacheck 
-cvuga` on a reboot but on looking in rc.sysinit it seems it will only 
force a quotacheck on boot when fsck finds problems with the disk.

Anyone know of a way to force this (touch a file etc.)?

Thank you in advance

Dan
