Is there any way to assign all permissions to a certain group without doing it individually? I want to make it so that on my Bukkit server, Head Admin and over have all commands automatically and no need for OP.
After the permissions rework, this is not possible without the use of an external permissions mod.
However, I'd like to note that this is NOT a good idea. In fact, this is why the ability to give the * permission was removed in the rework.
Some plugins will use permissions not as a way to enable commands but as a way to enable certain features, which you may not want. I could for instance make a permission like
antiCheat.user.preventFlying that would stop anyone with the permission from flying. This would be desirable for ordinary users but potentially undesirable for admins.
