Raspberry Pi 3 B+でFreeBSDを動かしたメモ

とりあえず雑に書き散らかします。

  • インストールイメージはWindowsからであればFreeBSDのマニュアルによるとImage Writer for Windowsとかで書き込める。
  • 最近のRPI3+はデフォルトでUSBブートが有効化されているので、起動イメージを書き込んだUSBメモリを刺して起動で大丈夫っぽい (古いロットに当たった場合は手動で)
  • USBメモリとの相性とは思われるが、mountrootが動くタイミングまでに/dev/da0が認識されないケースあり。この場合mountrootのプロンプトが出たら「ufs:/dev/ufs/rootfs」と入力してあげれば上がる。
  • 初回ブート時はUSBメモリのFSリサイズが走るので結構時間がかかる。
  • mountrootのタイミング対策は/boot/loader.confにdelay設定を入れればOK。↓このへん参考にした。

    forums.freebsd.org

    kern.cam.boot_delay=30000
    kern.cam.scsi_delay=30000
  • RPI3+のWiFiには現状対応できていないため、NWに繋ぐにはEthernet経由になる。手っ取り早く繋ぐには、たとえばラップトップのWiFiとEthernetをBridgeして紐で繋ぐとか。
  • nslookupとかdigが無いぞ。。。どうしよう → FreeBSD 10.0からBINDがベースシステムから除かれたのを忘れてました
  • freebsd-updateは現状使えない。ざんねん。

  • pkgも使えない…かと思ったら使える。ただし四半期更新っぽいので最新のpkgを使いたいのであればportsを使う必要あり。ただしUSBブートの場合はI/Oが遅いので要注意。またportsでビルドしようとするとautoconfのビルドに当たったあたりで依存関係のループに陥るので、autoconfぐらいはpkgで入れたほうが安全。一度入れてしまえばportsから更新できるし。またpkg versionとか叩く場合はpkgからca_root_nssをいれておかないとpkgの情報の入っているサーバのLet's Encryptの証明書検証でコケるので注意。また予めntpdateでシステム時刻を合わせておくこと。
  • デフォルトではIPv6が有効化されていないのでrtsol -Fで有効化してあげる必要あり。rc.confでifconfig_if名_ipv6の設定を入れてあげると自動的に有効になる。

とりあえず上げるだけなら多少の罠はあるものの難しくはなかった。今後はどの程度元気に動いてくれるのかいろいろ試したい。

あとCPU性能を見たいのでなにかベンチになるもの探さないと。

一応、dmesgはこんな感じ。
