You are correct, externals will break if the URL to the repository
changes. I am not aware of a way to avoid this. I do not know if you
can easily edit it after the fact, for example by editing the output
of svnadmin dump. Subversion does not support relative paths in
external definitions yet; it's an open feature request. Suggest that
if you change URLs, you then visit all projects where you've used
externals and update the definitions. Also suggest you pick a URL now
that's unlikely to need to change. (For example, pick a new hostname
like svn.example.com, even if you're currently hosting it on the same
machine as other things; this way you can break it off onto a
separate machine later should you wish to do so.) This also includes
deciding what server protocol you're going to use.
Ideally we would like to have the externals point to a relative path or be
able to edit the external at the server if the server moves. But until then,
you can checkout without externals (--ignore-externals), edit the
svn:externals and check-in changes, right?
------------------
The way I understand it, that will update the head, but old revisions will
still be broken. Is it possible to use a file:// URL which points to a
directory that can include the tilde (~) home-dir symbol (e.g.
file://~/repos/etc), or alternatively to a sym-linked directory (e.g.
file://home/me/repos/symlinks/etc where ~/repos/symlinks/etc points to
~/repos/etc) so that it can be repointed if the server structure changes.
