The command to downgrade your commit is:
git checkout c576847
This should be executed in the Minecraft script directory, which is …different I guess in the FreeNAS plugin. If you don’t think you can manage the downgrading/upgrading node, I recommend not using FreeNAS until the plugin author gets the plugin node v4.0 ready. In the meantime, there are numerous alternatives:
- installing any OS and following the instructions on the wiki or
- using MineOS Turnkey, the distro I support and maintain.
MineOS as a FreeNAS plugin is great, but it’s in a particular state at this moment that makes it not ideal for those who don’t feel comfy tinkering with the filesystems and such. Soon (as in hopefully within a week or two), the FreeNAS plugin will be again a very simple way to get MineOS running when it comes shipped with Node v4.0
TLDR; don’t use the FreeNAS plugin until it is updated by the plugin author Joshua Reulig; use literally any other method for now.
