system reset it says it will delete containers, images, networks, etc... However it will also delete the graphRoot and runRoot directories. Normally this is not an issue, however in same cases these directories were set to the users home directory or some other important system directory. As first step simply show the directories that are configured and thus will be deleted by reset. As future step we could implement some safeguard will will not delete some known important directories however I tried to keep it simple for now.
