Hi, Right, my goal is to provide smooth transition from rescue mode to normal mode, you can fine tune the process using modules. 1, Command Now commands are unified, no distinction between rescue and normal mode. Commands has a priority value. For example, we can have two ls commands, one in kernel, the other in ls.mod. After normal.mod starts, command.lst is loaded so that it will choose the highest priority command automatically. Basic command don't use extra feature, their support is in the kernel. Extended command need to parse argument, for example, to translate --file to grub_arg_list structure. Extended command depends on extcmd.mod. Occasionally, command needs to use extra function. They can depend on misc.mod. misc.mod can be viewed as an extension to kern/misc.c, which provides common used function not suitable to be placed in kernel. 2. Reader Kernel contains rescue reader. After switching to normal reader, we has command history and auto completion. 3. Parser Kernel contains rescue parser. After switching to sh parser, we can parse sh-like scripts. 4. Menu viewer Kernel don't have menu viewer. After loading a menu viewer, we can display menu items. 5. normal.mod normal.mod runs the following process to switch to normal mode: loads dynamic commands from commands.lst loads auto fs modules from fs.lst register handler commands from handler.lst switch to normal reader execute parser.sh to start sh parser execute menu_viewer.text to start text menu viewer parse grub.cfg -- Bean _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
