Core image size with raid + lvm

Core image size with raid + lvm

It appears that somewhere between Ubuntu 10.04 and 11.10, the size of the grub2 core image when including raid and lvm modules grew slightly and no longer fits in the old standard 62 sector embed area.  Is this a problem that should be fixed, or is this combination of small embed plus raid and lvm considered unsupportable?

It's unsupportable. The image was small enough mainly because of
combination of sloppy coding and avoiding handling some legitimate cases
which resulted in bugs. You're welcome to try to decrease the size of
this configuration (there are few places where you can squeeze few
bytes) but it contradicts few other goal with this config, one of them
being speed of boot.
