Change the semantics of variable hooks. They now return strings instead of error values. * util/i386/pc/grub-setup.c: Include grub/env.h. (setup): Use grub_device_set_root instead of grub_env_set. * kern/rescue.c (grub_rescue_cmd_root): Use grub_env_set and grub_env_get instead of grub_device_set_root and grub_device_get_root, respectively. * kern/main.c (grub_env_write_root): New function. (grub_set_root_dev): Register grub_env_write_hook for "root". Use grub_env_set instead of grub_device_set_root. * kern/env.c (HASHSZ): Reduced to 13, because GRUB does not need many variables. (grub_env_set): Set ENV->VALUE to the result of ENV->WRITE_HOOK rather than calling ENV->WRITE_HOOK afterwards. (grub_env_get): Return the result of ENV->READ_HOOK rather than passing a pointer of a pointer. (grub_register_variable_hook): Change the types of "read_hook" and "write_hook" to grub_env_read_hook_t and grub_env_write_hook_t, respectively. Allocate the default empty string on the heap, because this string may be freed later. * kern/device.c: Include grub/env.h. (grub_device_set_root): Removed. (grub_device_get_root): Likewise. (grub_device_open): Use grub_env_get instead of grub_device_get_root. * include/grub/env.h (grub_env_read_hook_t): New type. (grub_env_write_hook_t): Likewise. (grub_env_var): Change the types of "read_hook" and "write_hook" to grub_env_read_hook_t and grub_env_write_hook_t, respectively. (grub_register_variable_hook): Likewise. * include/grub/device.h (grub_device_set_root): Removed. (grub_device_set_root): Likewise. * fs/fat.c (grub_fat_dir): Make a copy of PATH in DIRNAME, and make sure that DIRNAME terminates with '/', so that grub_fat_find_dir will fail if PATH is not a directory. * commands/ls.c (grub_ls_list_files): Remove the qualifier const from DIRNAME. Use the qualifier auto for print_files and print_files_long. If FS->DIR sets GRUB_ERRNO to GRUB_ERR_BAD_FILE_TYPE, try DIRNAME as a regular file. Put a newline only if there is no error. (grub_cmd_ls): Remove grub_ls_print_files, because this is not used. |

README
This is GRUB 2, the second version of the GRand Unified Bootloader.
GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more
robust, more powerful, and more portable.
Because GRUB 2 was formerly developed under the project PUPA, there
remain still many places where PUPA is used instead of GRUB 2. So
suppose that PUPA is a synonym of GRUB 2 for now.
See the file NEWS for a description of recent changes to GRUB 2.
See the file INSTALL for instructions on how to build and install the
GRUB 2 data and program files.
Please visit the official web page of GRUB 2, for more information.
The URL is <http://www.gnu.org/software/grub/grub.html>.
Because GRUB 2 is still in developmental stage, GRUB 2 is not for general
use (yet). For now, you can install GRUB 2 into a floppy by these
instructions:
$ configure && make
$ ./grub-mkimage -v -d . -o core.img _chain ext2
$ dd if=boot.img of=/dev/fd0 bs=512 count=1
$ dd if=core.img of=/dev/fd0 bs=512 seek=1
It would be easier to use Bochs <http://bochs.sf.net/> than a real
machine.
