Consequences of using single root user
The operating systems like Linux/Unix support multiple users who can work on the same machine
simultaneously. The multiple users can connect to the system via different terminals or
network connections.
The root user of the Linux/Unix system is the most privileged user. The file system in UNIX and
Linux systems is divided into multiple parts like /etc /usr etc. The /usr file system is the partition
with programs and unchanging dadta. /var file system is the partition with changing data like log
files, a /home directory is there to store the data of all the users. These partitions and their
configurations can be different depending on the configuration of the system hardware and how
the system administrator wants these partitions to be. These partitions can also be kept all in
single root system which was the case way earlier when there were less security constraints on the
file systems of the UNIX/Linux systems.
The root partition of the machine is file system which is specific for it and is stored locally. The...
