How to install NomadBSD to slice of HDD? For example, ada0s3…
Although FreeBSD can be installed in multiboot, NomadBSD requires full use of the HDD so you’ll cannot install it on a partition. See nomadBSD install on HDD - #5 by mario
Untested and trickily:
Install FreeBSD in the slice and test that multiboot works.
Install NomadBSD onto an USB stick, you need 2 sticks.
Install https://github.com/JRGTH/bemanager in both installations.
With bemanager backup the boot environment of NomadBSD and restore it in the FreeBSD installation.
Boot with the restored NomadBSD Boot Environment.
I’m sorry. Your system installed on ZFS?
