What is the best method to harden OpenBSD in a diskless mode?
I am going to use Librebooted X86 amd64 + Linux for a ZFS host, in a very minimum config like: https://dev1galaxy.org/viewtopic.php?pid=21098#p21098 short (30-50cm) direct dedicated Ethernet cable between Orange PI ONE and X86 host, a firewall on both hosts which allows only a single connection of NFS from a single specific corresponding IP address. X86 booted from ROM or from a very old SD card or even from a floppy (grub4dos). Everything which can be encrypted (actually only against disk firmwares) is encrypted by luks: system, ZFS pool devs, etc. What can be improved? >> OpenBSD can run diskless but not sure if it works well, that depends on >> your workload and opinion. > >OpenBSD works "well" as a diskless system (see diskless(8)).
