Ensure all users' home directories exist

FaibleNiveau 2Revue manuellecos

Description

Users can be defined in /etc/passwd without a home directory or with a home directory that does not actually exist. If the user's home directory does not exist or is unassigned, the user will be placed in "/" and will not be able to write any files or have local environment variables set.
