I've just taken the plunge and started upgrading my no. 1 empeg to a 40G capacity. Anyway, I've followed the FAQ instructions implicitly and came across a small problem. I decided to copy all my fids from the old drive to the new one and found the command shown in the instructions doesn't work. A quick BBS search turned up a thread discussing this very topic. To cut a long story short, my empeg is now copying the fids using:

cp -auvfx /drive1/fids /drive0/

Is there any reason why this isn't in the upgrade instructions?
