Your hook script issue was not because you used svnadmin hotcopy.

When migrating a repository between OSes, servers, processor
architectures, or BDB versions (though that changed at some point in
the last year or two I think), you should use svnadmin dump and
svnadmin load, NOT a plain hotcopy. This is outlined pretty well in
the fine manual. See
