spacemacs keeps asking me to install asciidoc layer when I open a .adoc file, which I don't want.
How can I turned that off?
And can I quickly uninstall the layer without restarting emacs?
Only install layers explicitly defined in the layer list - this will disabled prompting to install other layers dotspacemacs-enable-lazy-installation nil - it's at the top of the .spacemacs file
Try setting the above setting to nil and the SPC f e R to reload the Spacemacs config. That should remove the package
Otherwise I assume a package can be removed via the Emacs package manager

Thanks again! I'd prefer to disable this only for this particular package but if there's no other option then I'll disable it for all.
