Seems like I completely forgot the diff here. Sorry, this time it is attached. Changelog: 2009-12-15 Andreas Born * kern/env.c (grub_env_context_open): Reapply global flag for variables exported to the new context. This behaviour can be really annoying. If one boots to the grub menu, chooses the shell with 'c', loads the menu again and drops to shell again (i.e. created 2 new contexts), prefix and root are gone. Although they are still exported into the first new context, they aren't marked again global in that context. Therefore creating another new context (from within the first context) doesn't export prefix and root from the 1st context to the second context. Of course, that has to happen as the global flag is not set in the first context. I created the new contexts by loading a grub.cfg which doesn't touch prefix and root with the configfile command. The patch changes the behaviour to not only export variables to the new context instead they are exported to the new context and then marked as global again with grub_env_export. Hope the issue is understandable like that. Otherwise please ask.
