I'd like to set up a Live USB key that can be updated and I understand that to do this I need to allocate some persistent storage. However, from everything I've been able to find, this storage gradually gets used up, and recovering it is rather risky. I've also seen suggestions that this doesn't happen if the drive is formatted with a proper Linux filesystem, such as ext4, before the live system is installed. I'd appreciate it very much if somebody who knows what's going on could set me straight on this.

F20 booting to systemctl only
Suddenly one morning, Fedora 20 will not boot. It was fine on the previous evening shutdown, but the next morning, all I can get is this error:
Welcome to emergency mode! After logging in, type "journalctl -xb" to view
system logs. "systemctl reboot" to reboot, "systemctl default" to try again
to boot into default mode.
Give root password for maintenance
(or press Control-D to continue):
I've tried all three options. The journal does not contain any error messages that I can detect, everything looks fine. The other two options simply return me to the same prompt.
I get to the fedora symbol which slowly builds to the logo and then the screen goes to the above error. I ran GParted and had the program check each of the partitions - no errors. I booted with a Live DVD and tried booting from the local hard drive - back to the same error.
I have backups, so I'm not losing data, but am curious how this might have happened and what I may be able to do to correct it. Interesting problem that I've never run into with Fedora before.
Your help and suggestions are very much appreciated.

systemd service not working as expected
I am trying to set up a start up script to run at boot time.
Essentially, I have simplified the script to one command: "/usr/sbin/iptables-restore fw.txt"
where fw.txt was essentially generated by running "iptables-save fw.txt"
Here is the service file:
The iptables-restore runs fine from the command line (as root).
But if I run 'systemctl start fw.service", then list the iptables, I get this:
(obviously not what I want.)
FWIW: I originally had a bash script that loaded the iptables, as well as doing a few other things. But that also only worked from the command line.
What am I missing here? Please help!
TIA

What lies under those apps in gnome 3 menus?
In an earlier version of gnome, one could put commonly used programs in the top bar, and when one right clicked on the icons, one could discover what and wher the actual program was. but with Fedora 20 and gnome 3, I have a bunch of icons on the left, but I don't see how to tell what is supposed to happen when I click on one of them. Similarly, if I enter a name in the top search window, I get some choices shown as icons, which I can execute, but I can't tell what the underlying programs are.
I've asked about this before, and I used it to put some programs, like vuescan, in my list, but I can't now find what I learned at the time.
I need help now because I have an icon for google Chrome, but nothing happens when I click on it.
I don't seem to have it installed.
Can anyone tell me what is going on?

[SOLVED] No Graphical Environment at boot
I'm not certain this is the best forum, because the installation seemed to have gone well. These issues showed up a few days after.
To the point...
On boot I'm presented with the regular non-graphical Linux console and can log in as such.
If I run startx Gnome starts with no problem, though of course I never see the greeter.
This morning, before doing startx, I checked the X.org logs, and they were still dated from yesterday.
I believe it is configured to go straight into a graphical environment:
$systemctl get-default
graphical.target
I have reason to suspect a package which should be installed is not (and if so it's certainly my fault), but I'm not sure which packages are involved. Any tips and/or suggestions would be greatly appreciated.

Graphics problem with GTX660 (nvidia)
Hello! I got problems with graphics on my computer and I have no idea how to fix it. I've spent an entire day trying to fix it, but sadly, I'm not really a hacker.
Before I descibe the problem, maybe I should say that everything worked fine until I installed a regular update. After that I couldn't boot into Fedora because of some problem with systemd. I reinstalled Fedora 20 and that's when the problems began.
I've tried different drivers, but that just did so that I couldn't start Fedora.
The problem:
There are two symptoms, firstly, the graphics are slow, as if the CPU takes care of all the work, and secondly, sometimes the screen starts to mess up until it's just a bunch of one-colored squares and stuff (hard to explain).
In the beginning the screen got messed up very often, but then I disabled integrated graphics in the BIOS (and then reinstalled Fedora), and now it only happens occasionally.
Info:
I don't really know what's relevant but here are some info:
In "details" it says under graphics: "Gallium 0.4 on NVE6". I saw somewhere that NVE6 is a code for my graphics card (a GTX660).
Running "lspci | grep VGA" I get the following result:
Also found this one: "-qa *\nvidia\* *\kernel\*|sort;uname -r;lsmod |grep -e nvidia -e nouveau;cat /etc/X11/xorg.conf" which gave me this:
What's wrong with my computer?
I would really appreciate any help! :)

Pertinent materials:

Does anyone have any effective methods of cleaning/leaching the resulting stink out of the freezer/insulation itself?
I'd like to salvage the freezer ... but I'm not married to it. If it can't be cleaned, it'll be either dumped or donated to a lab somewhere.
Needless to say, these particular contractors are no longer on my Christmas Card list. <..:dis:..>

Problem after changing hardware 990FXA-UD3 mobo
My old system was dying, an AMD processor with 4 cores.
I took a chance and bought this mobo 990FXA-UD3 with an AMD %X-9370 (or somesuchlike) CPU but kept the same 3 TB raid (master with 3TB mirror, but you know how Linux fakes that and doesn't really mirror the two. But anyway...). Now, the new system will boot but after a random time, simply crashes with no response whatsoever. Only a full power-down will get it to start up again.
Also, Fedora 20 only sees 8 Gb of the 16 Gb installed. BIOS sees the full 16, and "hardware checker" sees all 16, but Fedora main (and it's programs) only sees 8 Gb.
I assume the two problems are interrelated.
I aslo assumed that Linux would load all new drivers as needed, like it used to do, but apparently it does not. I do not know how to kick it to load what it needs for the new mobo and memory. Any help, please?
Gotta go before this thing shuts down.
Thanks!

Mouse Cursor corruption - Fedora 20 - after yum update
Hello Everyone!
First of all I am completely new to this forum and to linux :).
So take into consideration that I know almost nothing about the terminal (if that is needed to fix the problem).
My current linux knowledge involves:
.I know how to install it
.I know how to start it
.I know how to start the terminal
.I know my su Administration password
So, yesterday evening I decided:
"I am tired of windows, and want to learn something new so lets try linux."
After a bit of reading, I decided that the Fedora distro is the one for me.
So I installed it and everything was fine and looking good.
So I ran "yum update" in the terminal.
After restart I noticed that my mouse cursor is now corrupted.
I Have a small square under the cursor and the cursor looks "compressed"
(See attached pictures)
Now, if I restart and go back to the older kernel (I guess? :confused:) It works fine, without the corrupted pointer.
There is now 2 different version in my grub boot loader (one called heisenbug, being the new version with corrupted mouse pointer)
I don't know what more info I can provide except my computer specs:
.Asrock x79 extreme 9
.Intel i7-3930k
.16 Corsair low profile 1600mhz DDR3
.Intel 120GB SSD
.Asus AMD 290 r9 DirectCUII
Thanks in advance for helping me :)

Streamtuner2 doesn't work at all anymore
Howdy,
Has anyone gotten Streamtuner to work lately?
As far as I can determine, the last time it worked properly was in F16 and it has been steadily going down hill since. :Y
The far simpler little ditty called radiotray is also broken, due to to a missing pynotify, which I don't know how to get.
Cheers,
