Which looks like it will be the case -- grub2 currently introduces new bugs and probably can't migrate without another upload which would put it behind kfreebsd-10 timing wise. I guess we could ask release to block it maybe. Also I think it's fine installing kfreebsd-10 10.1 on jessie and using that as long as you don't upgrade the kernel while running a 10.1 so the upgrade case should be fine right (grub will understand all needed metadata for booting the kernel if installing it was done on 10.0)? I'd still set a breaks on lower grub-pc on the next kernel update or something like that. > Or, trying to install a jessie system from sid d-i. > What we could do is set feature@lz4_compress=disabled in partman-zfs, > just temporarily, until the newer grub version migrates. Not sure how much work that is. If it's quick and easy I'd go for it.
