Details:
Invoking ‘grub-install’ with “--core-compress <anything>” produces the
error message “Option should have been recognized!?”.
$ grub-install --core-compress none
grub-install: --core-compress: (PROGRAM ERROR) Option should have been
recognized!?
Try 'grub-install --help' or 'grub-install --usage' for more information.
$ grub-install --core-compress bogus
grub-install: --core-compress: (PROGRAM ERROR) Option should have been
recognized!?
Try 'grub-install --help' or 'grub-install --usage' for more information.
*Fix:* In the file ‘util/grub-install-common.c’, at the beginning of the
function ‘grub_install_parse()’, replace the character constant ‘C’ in
the ‘case’ statement with the macro
‘GRUB_INSTALL_OPTIONS_INSTALL_CORE_COMPRESS’.
int
grub_install_parse (int key, char *arg)
{
switch (key)
{
/* case 'C': */
case GRUB_INSTALL_OPTIONS_INSTALL_CORE_COMPRESS:
…
Program output after the fix, with the same command line as before:
$ grub-install --core-compress bogus
grub-install: error: Unknown compression format bogus.
(Passing “--core-compress bogus” was just the quickest way of
demonstrating that the option parsing error was fixed. It also seems to be
functioning as intended:
$ grub-install --core-compress none --verbose <other-options…> <device>
…invokes “grub-mkimage --compression none”, as expected.)
