When upgrading from v8 to v9 and running RteLinkSyntaxUpdater (the one which changes the <link to <a href ) an error is thrown in the install tool:
#1203699034: A cache with identifier "azurestorage" does not exist.
This is caused most probably by the fact that install tool doesn't bootstrap all extensions, so ext_localconf.php from azurestorage is not loaded -> no cache definition present.
