I'm a student currently proposing for an opensuse gsoc project (http://en.opensuse.org/Summer_of_Code_2008#enable_ext4_file_system_as_boot_p...) This project aims at enabling ext4 file system as grub legacy boot partition for opensuse and others.
I downloaded the grub source package from http://download.opensuse.org/distribution/10.3/repo/src-oss/suse/src/grub-0....
Please pull in the latests sources from: http://download.opensuse.org/distribution/SL-OSS-factory/inst-source/suse/sr...
unrpm the complete archive and check out the grub.spec (rpm specfile).
After decompressing it, I found eventually several patches for old grub-0.93, and grub-0.95 etc.
Surprisingly, even some grub-0.97 patches don't work well, such as disk-by-ID:

My questions are: are these old patches applicable to grub-0.97? Does grub running in opensuse10.3 really uses these patches, or just some of them?
I don't think so -- please check the latests grub 0.97 sources, that are used in the upcoming openSUSE 11.0.
I know that grub legacy is no longer under development, but since I'm working on an opensuse project, I need to consult the opensuse community to make sure that my ext4 patch cooperates with other patches when it comes out.
Great -- please subscribe yourself to the opensuse-factory mailinglist, which is the main forum for development related topics. Thanks, Christoph. I shall post my further question there:-)
