Are the differences substantial?  I would argue that they are not, no.
However, to provide smooth conversion to ucf-managed config files with
support for three-way merging (the killer feature that makes ucf worth
considering), you need to have a valid baseline config to use, and this is
different for each of the three main upgrade paths I know of to the current
packages (dapper, gutsy, and etch).  So however trivial the differences
might be, for best results the initial ucf registration should be done using
the same template that applied at the time of installation (as best this can
be determined).

As soon as Ubuntu 8.04 releases with this support, we can drop the legacy
dapper and gutsy templates; and when Debian 5.0 releases, we can drop the
etch one as well.  In the meantime, just having the ucf support in place
means we can finally be proactive about tweaking things in smb.conf without
worrying about how to communicate these template changes to existing users -
so hopefully one of the side effects will be even greater convergence
between Debian and Ubuntu smb.conf files, for everyone's mutual benefit.
