When you become root, ssh will try to read keys from the home directory
proper for a new uid, regardless of the $HOME setting. The same happens 
when you specify "sudo rsync" remotely. If you setup the keys properly 
for root and allow it to login using ssh (eg. PermitRootLogin 
without-password), it should work fine.
