  Well, it turned out to be me forgetting the way AdvFs keeps
  it's config information. Too long since I was on that course!!

  The mistake I made was to create the spare filesets (i.e. on the
  spare system disk) with *different fileset names* from those on
  the live system disk. i.e. I overlooked the fact that the fileset
  name gets stored on the disk filesystem it belongs to (presumably in
  the .tags area).

  So, when it came to mount /usr and /var (using the normal
  live /etc/fstab that had been vrestored) it was looking for
  the original fileset names, which of course didn't match the
  temporary names that I had used to build the filesets on the spare disk.
  The domain names are not so relevant.

  Lots of people helped, and one or two hinted at this (including
  a suggestion to use dd to do the copy, which would of course pick
  up the fileset info too).

  It was Ahmed Elouassif and Oisin McGuiness who spelt it
  out though - thanks guys! And thanks too to Colin Walters
  who sent a script to automate this and pointed me to a
  best practice document he's writing :

E.HTM

  N.B this relates to *V5.0* only, but it does give a clear idea of the
  main general steps.

  Thanks to everyone below - hope I didn't miss anyone:

  Until the next time.. ;-)
