/var/emptyをReadOnlyに設定
baseをインストールに設定すると、baseインストール時にコケるため、このタイミングで設定する。
# zfs set readonly=on zroot/system/var/empty

# zfs set readonly=on zroot/system/var/empty

事前設定

予め、最低限の設定を施す。

参考にしたサイトとは違って、swap領域は自動マウントされる模様。バージョン差？

# vi /boot/loader.conf

vfs.root.mountfrom="zfs:zroot/system/sysroot"

vm.kmem_size_max="15360M"
vfs.zfs.arc_max="3584M"
# vi /etc/ssh/sshd_config
PermitRootLogin yes

PermitRootLogin yes

passwd, tzsetupでrootのパスワード・タイムゾーンの設定も忘れずに！

sendmailのエラー防止
# cd /etc/mail && make aliases
chroot環境をexit
# exit

Copy zpool.cache

ブートローダ用にZFSの情報をコピー
# cp /boot/zfs/zpool.cache /t/boot/zfs/zpool.cache

# cp /boot/zfs/zpool.cache /t/boot/zfs/zpool.cache
参考にしたサイトだと、zfs exportとzfs importってやってるけど、exportとimport自体無くなってるから、やらなくていいっぽい。

Home Directory

ユーザ毎にストレージプールを作成する場合、自動マウントを有効化しておくとZFSの恩恵が受けられる
# zfs set mountpoint=/usr/home tank/home

Done.
