Hi Charles,

http://grml.org/config/grml-autoconfig.1.html states this:
---
Without any additional boot parameters, the GCA at DCSDIR/config.tbz is 
automatically unpacked and DCSDIR/scrips/grml.sh is automatically executed on 
system startup. The noautoconfig boot parameter disables this automatic 
behavior.
---

I couldn't find a change modifying this behavior, so I'd say this should always 
have been the case. If it didn't work previously, it might have been a hidden 
bug ;-)
