The typical use case where space is a PITA is boot an LVM system without a separate /boot partition. There we don't have the ressort of using a blocklist (which is already bad), so embedding core.img is mandatory, but at the same time, we have to load lvm.mod in (possibly raid.mod as well), and then you see where I'm going... For example, with current CVS: $ ./grub-mkimage -d . biosdisk pc ext2 lvm -o /tmp/core.img && du -b /tmp/core.img 30511 /tmp/core.img $ ./grub-mkimage -d . biosdisk pc ext2 lvm raid -o /tmp/core.img && du -b /tmp/core.img 32940 /tmp/core.img The first is close to the limit (32256 B) and the second surpasses it, so boot from LVM on RAID with DOS label and ext2 is a use case we can't support right now. > I think lzo is working fine, we > should avoid switching unless there is a good reason to do so. ISTR Okuji didn't like it; can't remember why. -- Robert Millan I know my rights; I want my phone call! What good is a phone call… if you are unable to speak? (as seen on /.)
