第 18.2 节 系统安装
自树莓派 3B+ 开始，无需任何改动，系统即可从 U 盘启动，经过测试了 FreeBSD 12/13/14 都是支持的，但是速度非常慢，一方面树莓派 3B+ 使用 USB2.0 极大的限制的总线速度，另一方面可能是玄学问题。（测试用的是东芝（TOSHIBA）64GB USB3.0 U 盘 U364 高速迷你车载 U 盘）。
因此 3B+ 不建议使用 U 盘启动，慢的我要打年年猫，年年猫是谁？是一只调皮的野生狸花猫而已。
我们所有要准备的有树莓派 4 板子一块，网线一段，存储卡一枚。从 https://FreeBSD.org 下载适用于树莓派 4 的镜像:
下载后解压缩。使用 rufus 刻录。插入网线，将存储卡插入树莓派，通电等待约五分钟，查看路由器后台获取 IP。建议最后外接个显示器以免卡住了还不知道还在苦等。
注意： 刻录完需要挂载 FAT 分区 替换里面的所有文件，否则会启动花屏，替换的文件路径为：

【变通方案】FreeBSD 与树莓派 4B 8G 启动失败问题
如果卡彩虹屏不启动，下载 FreeBSD 14 镜像写入后将 FAT 分区内容替换即可（默认分区是隐藏的，使用 diskgenius 激活隐藏分区分配盘符即可）
https://github.com/FreeBSD-Ask/FreeBSD-rpi4-firmware
修改 config.txt 为以下内容：
arm_64bit=1
dtoverlay=disable-bt
dtoverlay=mmc
device_tree_address=0x4000
kernel=u-boot.bin
armstub=armstub8-gic.bin
hdmi_safe=0
force_turbo=0 #超频
arm_freq=2000 #超频
over_voltage=6 #超频ZFS 与树莓派
如果固件不是最新的，先使用树莓派官方系统更新下固件！
注意
FreeBSD 默认提供的 IMG 镜像使用 UFS 文件系统。想使用 ZFS 的用户可在存储卡上刻录好 img 正常启动。再插入 U 盘，加载 ZFS 模块。运行命令
bsdinstall正常安装（安装位置选择 U 盘）即可。如果想在存储卡上使用 ZFS，反过来用 U 盘进行安装即可。
安装前：（mmcsd0 为存储卡，da0 为 U 盘。要往 U 盘里创建一个使用 zfs 的树莓派 FreeBSD 系统）
使用正常镜像写入存储卡，启动后再插上空白 U 盘， U 盘保持 FAT32 ，MBR 分区表即可。

# kldload zfs开始安装：
# bsdinstall安装后复制固件即可，注意不要覆盖了 EFI 分区原有的东西。

该问题主要出现在用 zfs 的存储卡安装系统到 U 盘出现的，目前无解，只能用另一个 UFS 的 U 盘启动盘来安装 U 盘。
可能用到的命令：gpart destroy -F da2 摧毁这一步错误创建的文件系统，以防止系统不识别。
