If I create or modify a module, how do I prevent it getting overwritten on next update

I have modified the Help module and want it not to get overwritten on the next update. What can I do to tell update to leave the entire module alone and not update it. Is there an easy way to have an update bypass the module or do I have to list every file and form in that folder?

Thanks!

 

If you change existing files, they will be overwritten during an update. You can save your changes outside /usr/local/ispconfig/.../ and copy the files after an update. But make sure, that this will not break your changes. If think your modifications are usefull, you can commit your changes on git.ispconfig.org.
