TBD...

## Motivation

TBD... Platform/infrastructure project prototype.

## Installation

Virtualbox image (dev/dtrace enabled, incremental)
```bash
cd /usr/src/tools/tools/nanobsd

sh nanobsd.sh -n -c sbconf_devtrace.nano

VBoxManage convertfromraw /usr/obj/nanobsd.GENERIC/_.disk.full ~/freebsd_nano.vdi
```

Virtualbox image (dev/dtrace enabled, clean)
```bash
cd /usr/src/tools/tools/nanobsd

sh nanobsd.sh -c sbconf_devtrace.nano

VBoxManage convertfromraw /usr/obj/nanobsd.GENERIC/_.disk.full ~/freebsd_nano.vdi
```

Virtualbox image (production, clean)
```bash
cd /usr/src/tools/tools/nanobsd

sh nanobsd.sh -c sbconf.nano

VBoxManage convertfromraw /usr/obj/nanobsd.SB0001/_.disk.full ~/freebsd_nano.vdi
```

Virtualbox will have the following config requirements:
* 2 CPU cores (so Erlang runs in SMP w/o additional flags)
* 640MB RAM (sufficient for dev/test, production running ZFS should have more)
* SATA or SAS disk emulation (legacy IDE disabled in SB kernel, legacy SCSI is slower)
* 2 Network adapters (Intel PRO/1000 MT, bridged to actual device for external NTP access)
* 1 Serial port enabled (for secondary terminal, socat/screen access {https://gist.github.com/snb/284940/11e6354f170be602c9c2f67b59d489ed49ebd143})
