Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I used an Emacs within a console (no GUI). Yes the file was saved. There even was the backup file Emacs created for me. And I managed using that edited fstab right after fiddling with it. I.e. I could mount the newly entered partitions. But not only was the fstab changed back once I rebooted the machine, also the directories which I had created as mount points ("/c", "/d" and "/e") were gone.
well he would have to be root regardless cause if he was non-root, he would of gotten an error message of permission denied when trying to save the file and when trying to make a folder in /mnt..
the only thing i have seen referenced to this is by disabling kudzu otherwise i don't know.
Oh, and another curious fact about those mounts: I create the directories which serve as mount points, then I mount the partitions. So far, so good, so tasty.
So why is it I cannot write to any of those mounted partitions unless I am root. Oh, I get it, the access rights to those directories are write-only for non-roots (or rather: non owners).
Well, hey, I am root, ain't I? So it should be a piece of pie changing those rights? Yeah, or so I thought. Redhat just laughs and tells me that I am not allowed to change the rights to write access? Then what am I root for?
What are you mounting? Certain filesystems don't support permissions, so they're "stuck" on certain permissions. You specify permissions for these by putting "umask=<number>" in the options of fstab. Whatever permissions you specify here applies to everything in the filesystem.
