That's not what "svnadmin help load" says. It says it will use the
UUID in the dump automatically, assuming the repository was just
created and is empty. And if the repository you're loading into is
not empty, then forcing the UUID would seem to cause a disaster,
since the repository the old working copies expect to find is not the
one they're going to find (revision numbers will have changed, etc.).
$ svnadmin help load
load: usage: svnadmin load REPOS_PATH
Read a 'dumpfile'-formatted stream from stdin, committing
new revisions into the repository's filesystem. If the repository
was previously empty, its UUID will, by default, be changed to the
one specified in the stream. Progress feedback is sent to stdout.
