In fact, that's what I was dreading to hear. I think I'll have to do a reinstall at some stage putting boot on a RAID array.

Also, I should have said this before: Thanks a lot for submitting your patch in the first place, it was very helpful, indeed! > cheers, > guillaume Best regards, Andree -- Andree Leidenfrost Sydney - Australia
