AFAIK, grub-installer (the udeb package) already has logic to install correctly on RAID systems, by using the underlying devices. This should be writing grub-*/install-devices as well, which should be taking care of package upgrades.
diskfilter writes not being supported in grub is certainly not something new; so let's figure out why this is now becoming an issue when it was not typically all that critical in the past. But yet more importantly, why do we need another bug than https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1274320? I think this correctly describes the situation, and any work on having grub support RAID (or gracefully handle the fact that things are on RAID and thus can't save_env), should probably better go on the original bug. ** Changed in: grub2 (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1756517 Title: grub-install: error: diskfilter writes are not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1756517/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
