I personally think another, much safer option is to make use of flag "--user-data-dir"
Code:
chromium-browser --user-data-dir=/foo
I created a chromium-profile directory in /root/ to hold the different profiles. You can also append that to any shortcuts with the menu editor in gnome.
I created profiles for pentesting, developing, and normal use. I don't trust running anything associated to Google with root privs.

Here are a few links regarding that:
