Hi, i recently advertised grub-mkrescue as replacement of script snippets for creating ISO images with legacy GRUB.
But it is not very appealing to the audience if i have to mention the different interpretation of argument "--" by the shell script of GRUB-2.00 and by the C program of the git master branch. The C program demands "--" before any custom options for xorriso -as mkisofs are accepted. Omitting it lets argp_parser() return ARGP_ERR_UNKNOWN rather than adding the mkisofs option to the xorriso argument list. The shell script forwards "--" to xorriso -as mkisofs, where it ends the mkisofs emulation. Afterwards, the additional mkisofs options are not understood by xorriso. We discussed this a while ago in the thread following http://lists.gnu.org/archive/html/grub-devel/2014-01/msg00074.html There was no conclusion. If this CLI change shall persist, then there needs to be some indication for scripts, whether the "--" is mandatory or harmful. Further, the documentation of grub-mkrescue needs to be updated. Including the help text in the C code, which currently describes the behavior of the shell script. In my personal view, it would be better to keep the behavior of GRUB-2.00. E.g. by replacing in grub-mkrescue.c line 229 return ARGP_ERR_UNKNOWN; by a call of xorriso_push() ... i guess ... Have a nice day :) Thomas _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
