emerge --unmerge
uninstalll all files except the configuration files you changed.
bad things: portage does not check other pkg which depends on the to-be-uninstalled pkg.
origin:'''When you remove a package from your system, the dependencies of that package that were installed automatically when you installed the software are left. To have Portage locate all dependencies that can now be removed, use emerge's --depclean functionality. We will talk about this later on. '''

[emerge --update world] 更新全系統
[emerge --update --ask world] 先問user再繼續
在我的系統，它只看gcc, glibc
[emerge --update --deep world] 更新系統上'''每一個'''套件
不過，用這個指令，它還是只看gcc, glibc
'''Portage will then search for newer version of the applications you have installed. However, it will only verify the versions for the applications you have explicitly installed (the applications listed in /var/lib/portage/world) - it does not thoroughly check their dependencies. If you want to update every single package on your system, add the --deep argument: '''

I don't know the reason. Reboot.

free inodes 只剩68，可能是 root cause

把一些目錄移走，終於騰出387個inodes，也解決了問題
