Hi,
I've a laptop with Ubuntu 14.04/OpenBSD-current dual boot.
I'm trying to convert the OpenBSD FS to softraid(4) encryption with
passphrase.
I'm booting from an USB drive to access the disk to shuffle data on
it.
After backing up my data, changing the OpenBSD disklabel in sd0 to
have one RAID partition and one swap partition, running bioctl to
setup an encrypted sd2 softraid and restoring my data, I'm stuck with
bootblocks.
What is the correct installboot incantation to setup bootblocks so
that Ubuuntu's grub which chainloads the OpenBSD part of the disk
loads a softraid-aware biosboot ?
here is the detailled layout of my disk:
