I'm not sure I like a web-based interface.  This makes automated
installations and testing much harder.

I don't like that approach either.  I prefer an approach like this:

1) make

2) make install

3) ledgersmb-init-database

That is, have a dedicated command-line script that initializes the database.
It can be interactive, but should also take command-line options for a
fully-automated setup of the database.  The ledgersmb-init-database
script should do sanity checks to see if there's already a database, etc.
If it does find a database, it can offer to do a schema upgrade (or
do it automatically if so told by a command-line option.)

This has the nice side-effect of making the upgrade procedure
absolutely identical to the initial-installation procedure: make;
make-install; ledgersmb-init-database.

I don't think it's a good idea to depend on those for systems on which
we deploy.

Administrative task, for sure.  Otherwise packaging LedgerSMB as a .deb
or .rpm becomes difficult.
