[Utility] - Script to generate kickstart %packages section

by Davidson Paulo

Hi, I was wondering about an easier way to include all packages actually installed on system in the %packages section of a kickstart file, using as few lines as possible, with groups, individual packages and exclusions, so I decided to create a BASH script to help doing that: getPackages.sh. If you want to test, just download it, give execution permission, take a comps.xml file and run it, as follows: $ chmod +x getPackages.sh $ su -c 'yum makecache' password: $ zcat /var/cache/yum/fedora/Fedora-9-comps.xml.gz > comps.xml $ ./getPackages.sh You're all welcome to test, modify and redistribute the code. I hope this can be useful.

F9 livecd: Danish keyboard?

by Mogens Kjaer

I'm trying to make a respin of the F9 livecd. This should have Danish keyboard as default. I've tried the trick on: https://www.redhat.com/archives/fedora-livecd-list/2008-May/msg00014.html by adding /usr/bin/system-config-keyboard --noui dk >/tmp/keyboard.log 2>&1 to the /etc/rc.local file. I get the response: Loading /lib/kbd/keymaps/i386/qwerty/dk.map.gz in the logfile, but it's still set to US keyboard. If I run the command above after logging in, it works. How do I set this up automatically?

It will be inserted to the right left of the workspace switcher and other icons next to the clock. This was mentioned in the previous threads. It takes getting used to it.

Is there any possibility of Official Fedora Live CD to have Easylist

by Antonio Olivares

Dear all, I have checked out other livecds. I have tested for instance the Kubuntu LiveCD. I tried konqueror and to my surprise there were no adds the internet experience was awesome. I checked out the Adblock filters and they had a file called Easylist http://easylist.adblockplus.org/adblock_rick752.txt Is there any possibility of incorporating it in to Fedora's LiveCD? It stops a bunch of popups/ads that clog up the internet experience. It was included in konqueror. If the answer is no, then I apologize for asking as I can add it manually, but it is not for me, but for other potential Fedora users. I use Slax Linux Live CD as well and there I manually set it up and I browse without any distractions that would otherwise slow down my internet experience. I think the incorporation of this would make browsing experience better for potential users. My $0.02 Regards, Antonio

Question

by livecd＠mjkern2000.fastmail.fm

I am looking for something that will make a kickstart config file for Fedora based on an installed and patched system that has all the configs and software installed that I want. Then I would like to build a live CD based on that workstation that would run on that same device (but without the hard drive, as the hard drive removes. I would put a flash drive there and do some sort of 'frugal install' onto the flash drive to boot the system) Then when I wanted to upgrade the system, I would put the hard drive back in, update and build a new kickstart config file, make a new live cd. Is this possible? What tools do I need from a kickstart standpoint to take a snap shot of a working system? I know how to use (or can figure out) the Livecd tools with kickstart and I can figure out how to make a frugal install of fedora livecd's on a flash drive, but I don't know how to make a kickstart snapshot. I could manually make a kickstart file that installed the software, but i am interested in having my background done, the menu changes saved, the wireless settings saved. I have to put a wep key in for my wireless to work and an too stupid with kickstart to know how to do that kind of stuff or where to look. Is this scenario possible, and where to do I go? -- mjkern2000(a)fastmail.fm
