[Evolution] Move Evolution disk

[Mark Stanton <mark stantoncentral co uk>]

My Evo setup is on the only disk in a (Linux) machine.  I want to move
it to be an "additional" disk in a server.

I can easily do this and mount the email/&tc files in the right places
on my workstation but I can't then access them because the wallet fails
to unlock (I think).

Is the fix as simple as (re)moving the wallet file?
