However, "kfreebsd > /@/boot/kernel/kernel" is on a ZFS dataset. Then it should be sufficient to have 'insmod zfs' in grub.cfg.

There are patches in the current FreeBSD port to fix that. These patches were integrated upstr= eam in later versions. >>> You don't need libzfs to use grub2 on ZFS. > Please clarify: Do you mean that I don't need to invoke "--enable-libzf= s"? > If so, why do I get the error above (no labels found)? You definitively don't need '--enable-libzfs'. On FreeBSD, this will look for some non-existent include file and fail. This option seems to be used by folks running Linux on ZFS. And just a remark. I think the current version of grub2 in the ports could be sufficient for your need. With version 2.00 you gain the ability to install grub directly on ZFS, but since you don't use that.. > Thank you for the input & Regards. > > > > -- > View this message in context: http://freebsd.1045724.n5.nabble.com/grub= 2-with-libzfs-tp5799405p5799443.html > Sent from the freebsd-ports mailing list archive at Nabble.com. > _______________________________________________ > freebsd-ports@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-ports > To unsubscribe, send any mail to "freebsd-ports-unsubscribe@freebsd.org= " --=20 christian.mangin@gmail.com - PGP: C850892A
