use `linuxconf' This is a configuration facility that works both in shell
as well as X.

I guess the user has to create homepages in his/her respective directory
/home/xyz

The default settings of Unix/Linux is that almost all of the system is
accesible for read-only by all users. If I am right (I only use Unix,
never studied about its structure), some of these have to be read-enabled.
A few of them can be disabled by `chmod' option (read the manual - man
chmod) Also use `man ls' to understand the meaning of the listing method
rwxrwx---  etc.

I guess some system files (like /usr/bin and /usr/passwd) have to be read
by the user's process while running - you just can't cancel this access.
But any user cannot modify these files - only root can.
These are standard Unix features. Perhaps you can look a little more into
them.
