Problem

Some commands like volt get, volt rm, ... could modify files under $HOME/volt and $HOME/.vim with root privilege.
It can cause a problem when volt accesses to the files (e.g. permission denied).

Solution

Volt must not creates files with root permission under /home/{user}/volt, /home/{user}/.vim.
