位置在 /etc/vimrc 中，不过这个是全局的。
个人用户的位置就在 ~/.vimrc。
注释使用的是 " 用一个双引号表示注释。
下面是我的一些个人配置：
" All system-wide defaults are set in $VIMRUNTIME/archlinux.vim (usually just
" /usr/share/vim/vimfiles/archlinux.vim) and sourced by the call to :runtime
" you can find below. If you wish to change any of those settings, you should
" do it in this file (/etc/vimrc), since archlinux.vim will be overwritten
" everytime an upgrade of the vim packages is performed. It is recommended to
" make changes after sourcing archlinux.vim since it alters the value of the
" 'compatible' option.
" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages.
runtime! archlinux.vim
" If you prefer the old-style vim functionalty, add 'runtime! vimrc_example.vim'
" Or better yet, read /usr/share/vim/vim80/vimrc_example.vim or the vim manual
" and configure vim to your own liking!
" do not load defaults if ~/.vimrc is missing
"let skip_defaults_vim=1
