Hi, grub-mkrescue is quite useful, however, I'd like to be able to customize the image it creates a bit more than it currently supports. In particular, I'd like to load another config file at boot time. The attached patch enables this by way of a new option, --configfile.
A more general solution to the customization problem would be to load a config file at image compilation time. This could be used to solve my problem. However, as it is an additional level of indirection, perhaps both options would be useful. Thoughts? Thanks, Neal 2009-01-17 Neal H. Walfield <[email protected]> * util/i386/pc/grub-mkrescue.in: Add new option --configfile. If not the set and not the empty string, load it from the generated config file on boot.
