First you need to mount the disk you can do this on the terminal as root or with sudo

Will asume your root partition is on /dev/sda2 you need to figured that out first create a folder inside /mnt/ folder to mount the disk, since you are running a fedora on USB you could use a graphic tool to mount the or auto mount the disk else do as follow

sudo mkdir /mnt/mydisk

sudo mount /dev/sda2 /mnt/mydisk

once disk is mounted

cd /mnt/mydisk

with ls you should see all the folders and files from the disk so

you change to /etc

cd /etc

and usen nano or vi to edit the file you need to change.

Good luck

Hard disks drives contain partitions, and each partition contain a filesystem.

In Linux and Unix there is a main filesystem called root filesystem, and indicated with /. Other filesystems (real or virtual) are mounted on the root filesystem on a mount point, i.e. an empty directory used as a start point for the specific filesystem, in such a way that all files can be reached as descendant of the root directory.

So, In plane English for novices like Me, this means that instead of changing "Drive" by uising a D: command for instance and physically moving the Target of focus to a physical disk, you simple Change directory to the "Mounted" filesystem, which by default in Fedora 21 appears to be under the /run/media/ dirctory Do not forget that you have to MOUNT the drive first either manulaly or by editting an dadding the details to the fstab file.

And to see mounted filesystems and relevenmt info you may need, type " lsblk -f " in a terminal window and see the ID of the disks. It isa the Label that you will search for in the media folder if it has been mounted using that

I'm guessing that you want the cd command:

cd etc

If you don't know something that basic, you should read some command-line and shell tutorials.

Actaully, I think you'll find the answer is all about MOUNT and Where the file system is Mounted, usually under the /run/MEDIA folder / Directory.. buyt thanks for the tiips - The simple way of Answering this, as I just found out, is to understand the filesystems. We all had to start somewhere you know and once upon a time, YOU knew nothing either. If you ever need any help with a "Windows" - just ask and I sjhall answer politly
