OK - I see how this works, but it's quite a bit of work to redo whenever the
default setup changes. Not sure how often that will happen but it could be
an issue. Is there maybe some way of doing this by playing with the
relocate/switch statement? The currently proposed solutions are not
currently simple enough for my purpose - I want to be able to have a
'default_repo' that gets tweaked and modified as required, and for my
createrepo script to seed a new repository with revision 1 that matches the
head of default_repo, with no user intervention required.

If that is not possible, then I will probably get my script to manually
construct the first revision in a temporary working copy, commit that and
delete it. This would mean that any modifications would need to be made
directly in my setup script rather than in a versioned repository, but this
is probably the simplest solution if I can't automate the above.
