User nobody is a user used by many system programs. It is a convenient user
id for system programs to be run at if they do not have to be root; also
some programs begin as root, use root to get ahold of the resources they
need, and then change their id to nobody. In both cases it is to minimize
the damage that can be caused by a bug or security problem in the program.
