Are there any sandboxing mechanisms (like docker) that will let me create a portable sandbox? Basically all my libraries/executables/consistent content stored in single file, where I can just start/stop the file like it was a virtual machine?

Lets say I want to run Wordpress. I'd like something that can wrap apache, php, mysql, databases and web content all in a single file that I could copy from machine to machine or even duplicate and run two independent version of the wordpress site

I use it for testing puppet manifests in an automated build system so my use case is slightly different to the normal docker use case. I need it to look as close as possible to a full machine.

Help Needed  - 
 
Hey everyone, I'm not sure which community I should ask this in, but since it's Linux related, I'll post it here and hopefully someone will know what to do.

I have 3 SATA HDDs in my PC, a 500GB which I want to install CentOS, and two NTFS drives (1.5TB and 2TB) that are used for storage data. 

I tried installing CentOS, but my computer kept halting at "Verifying DMI pool...."  I couldn't understand why, but after some trouble shooting, I discovered that if I removed my 1.5TB drive, the computer would boot properly. Somehow, even though the 1.5tb drive is the last in the HD priority order in the bios, it is still preventing my PC from booting. 

I think grub somehow got installed on the 1.5tb drive as well, because when I removed my CentOS drive and only had the 1.5tb in, I got a grub error because there was no operating system.

So my question is, how do I remedy this problem? I don't want to format that drive because I have data on there that I want to keep.

+Gavin Lobo I'd use ext4, in fact if you have no use for ntfs, my plan of action would be to move the data to one drive, format the empty drive to ext4, move all the data on to that drive and format the other drive to ext4, keep in mind that if you still need to access the drives with windoze you'll have to stay with ntfs, windoze can't read ext4.........................

Recommending Hardware  - 
 
Hi everyone,

I'm looking to build a gaming computer soon, and I have pieced together pretty much everything that I want, except the motherboard. Do any of you have any recommendations on what motherboard is good with a core i7-4790K cpu and is very Linux friendly. I don't want to have any issues trying to boot into Linux because of some stupid bios issues or whatever. 

Ideally I'd like something less than $200 CAD, and has at least 8 USB ports on the back, ATX sized. I'd like to shy away from Asus, I've had problems when them in the past and I'd rather not have to deal with them again. I'm looking at MSI Gaming 5 at the moment. It says it supports SteamOS, so I'm assuming it's Linux friendly...Any thoughts on this?

+Christopher Waid Mostly personal preference. Other than gaming and browsing, I usually use command line for everything else so I don't need a heavier desktop. I've been using Xfce (+Fedora) on my laptops for some time now, so I'm used to it. I've read about some people having issues with Unity/Compiz in some games, but I didn't like Unity so I didn't use it enough to test.

Help & Support  - 
 
I'm having trouble installing the Nvidia drivers from Nvidia's website. I wanted to use the .run file provided. I followed the steps given here:

https://en.opensuse.org/SDB:NVIDIA_the_hard_way

What I did was:
1. added  "blacklist nouveau"  to the end of /etc/modprobe.d/50-blacklist.conf

2. added "modeset.nouveau=0" to the end of  the Optinal Kernel Command Line parameters in the Yast Boot loader options.

3. Restarted  and shutdown X using "rcxdm stop".

When I tried to run the .run file, the installer still said Neauveau was still running and it would exit.

Any help on this would be appreciated.

all you have to do using the .run file is uninstall nouveau via yast. reboot, press escape after grub boot into your system. this the way i get a terminal. login as root and install the .run script. this is the hard way i allways do to install the nvidia driver... hope it helps... forgot to say blacklist the nouveau via .conf first...

CentOS-7  - 
 
Hi everyone, I'm giving CentOS7 a try for my server and I REALLY want to like it, but it's giving me nothing but trouble for the past two days.

I have a NTFS drive, that I would like to mount, and then share that mount over the network using samba. Here is my fstab entry

/dev/sda1    /mount/krypton   ntfs-3g     rw,auto,user,fmask=0022,dmask=0000,uid=0,gid=0 0 0

And here is my samba entry:

[krypton]
 path = /mount/krypton
 browsable = yes
 writable = yes
 guest ok = yes
 read only = no

I know I'm missing something, either with SELinux or with the permissions, because I can see the folder when i connect to the server, but I cannot see any of the files within.

Glad I stuck with 6.6 for now, I haven't heard many stories where getting up and running with 7 went smoothly.

How would I go about preventing MDM from starting on boot? I still want to be able to start it if I need to, but I don't want it to start automatically

I finally found a way to do what I needed.

Had to edit the /etc/default/grub file, and change the line 

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="text"

Anyone have any opinions on mechanical keyboards? I'm looking for one to replace my Logitech G15 that I've had for many years.  I really liked the RGB keyboards, but I think they're a little expensive and the two that are available (cosair/razer) lose the RGB functionality on Linux since software they come with only works on windows.

So what I would like is something that looks good with some nice backlighting. I will mostly use it for programming/playing games. I heard Cherry Reds are good for gaming, but I'm not a professional gamer, so I wouldn't even notice the difference compared to what I'm using now. I don't use the G keys on my G15, so I don't need anything super fancy.

I heard the clicky keys can be annoying when playing on Ventrillo since people on the other end can hear the clicks.

So any suggestions on which one would be good for me?
