There are two additional volumes that can be mounted; `/mods` and `/config`.
Any files in either of these filesystems will be copied over to the main
`/data` filesystem before starting Minecraft. If you want old mods to be removed as the `/mods` content is updated, then add `-e REMOVE_OLD_MODS=TRUE`.
`/data` filesystem before starting Minecraft. If you want old mods to be removed as the `/mods` content is updated, then add `-e REMOVE_OLD_MODS=TRUE`. If you are running a `BUKKIT` distribution this will affect all files inside the `plugins/` directory. You can fine tune the removal process by specifing the `REMOVE_OLD_MODS_INCLUDE` and `REMOVE_OLD_MODS_EXCLUDE` variables. By default everything will be removed. You can also specify the `REMOVE_OLD_MODS_DEPTH` (default 16) variable to only delete files up to a certain level.
> For example: `-e REMOVE_OLD_MODS=TRUE -e REMOVE_OLD_MODS_INCLUDE="*.jar" -e REMOVE_OLD_MODS_DEPTH=1` will remove all old jar files that are directly inside the `plugins/` or `mods/` directory.
This works well if you want to have a common set of modules in a separate
location, but still have multiple worlds with different server requirements
in either persistent volumes or a downloadable archive.
### Replacing variables inside configs
Sometimes you have mods or plugins that require configuration information that is only available at runtime.
