I installed Linux redhat v7.0 for checking its abilities.
It has a good and frienly environment but I find some bugs that has
been listed below:
1- in your PASSWD command at first you must ask old password after that
(if it was true)you want New password.
2- last week when boot> prompt appeared I entered LINUX SINGLE and
perssed Enter in this case after # prompt I had root abilities and I
changed root passwor (with PASSWD command).
So,your OS security is Low(I think) but I really like Linux.
I must tell you that I sent this mail Last week but it was rejected
(because I entered (email@example.com)without "m" in "com").

It's intentional; if you have console access to lilo, you can boot up
as root anyways.
You might consider setting a password in lilo if you don't like this idea.
