dracut 沒 include 到 LVM module 開機失敗
gentoo要USE FLAG在LVM2 +lvm才會build出/sbin/lvm
繼而讓dracut偵測到的樣子
要仔細檢查dracut的output才行
lsinitrd 也可以檢查是否有include到module
haproxy 2.7.2 啟動失敗
http-use-htx 選項被移除 直接把這行從config裡面刪除

不確定成因，猜測會造成影響的只有kernel， 官方給的指引也像是kernel，雖然試過完全沒用
升級到2022版就解決了，幸好不用退kernel版本
直接從2017升上2022會觸發assertion failed崩潰，但先退回2019跑一次以後再改成2022就可以順利執行，謎一般的升級機制…
pfsense slave 的 TLS 憑證過期了 HTST 導致連不進去 web ui
老問題了，重啟web ui解決
雖然master的ACME會去更新憑證，也會sync到slave上面，但必須重新啟動才會換掉
crontab加一個 /etc/rc.restart_webgui
ubuntu PUBKEY issue
默默地又過期了，22.04上的key管理有點改變，只好修了
親測kubeadm kubelet kubectl這三板斧的apt source就用下面這個
sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg
echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
ref. https://blog.zeroplex.tw/2022/10/15/build-kuberenetes-cluster-on-ubuntu-22-04/ https://zhuanlan.zhihu.com/p/507673339
ubuntu upgrade to 22.04
也不算甚麼大問題
kubeadm kubelet hold版本以後因為沒有全部更新到最新版 被擋住不能更新
也可以把apt source刪掉
不過20.04還可以用到2025年 乾脆等k8s 1.26多幾個版本號再一次更新上去吧
gentoo upgrade world
從2022年初升過來
確定portage超過3.0.20，個別套件升到下面這個版本，就可以跳到最新進度一次編world了

說要指定disk甚麼的，還是加個–removable省事
