Centos Kickstart Installation From Usb
Kickstart and Cobbler on CentOS Server. What we are starting with OS Version: CentOS 6.3 minimal install from CD Hostname: puppet.example.motorrobot.net Static IP: 192.168.7.2 SELinux disabled. To test that the syntax was correct I placed the kickstart file on another USB stick and loaded the same command to grab ks.cfg from the new location: linux ks=hd:sdc1:/ks.cfg This does work (providing USB sticks are mounted in order, boot -> sdb1, kickstart -> sdc1). The install will kickstart and complete the install with no issue. Making Installation USB Media. Making Installation USB Media on Linux; 3.2.2. Making Installation USB Media on Windows. If you have a Red Hat Customer Portal account. The Kickstart installation must access an installation source in order to install the packages needed by your system. Kickstart from USB stick. If you leave out the kickstart boot options, does the normal non-kickstart installation start successfully? I dug up my old notes about setting up a RHEL 5.x Kickstart USB stick, and in RHEL 5.9 and above I hit the same problem you had: the ISO is more than 4 GB in size, so it's too big for FAT32.

I was wondering if anyone has managed to do a network install where the
kickstart file is located either on an FTP site (which is also where the
packages are stored) or on a USB flash drive.
I've tried starting the installer with 'linux ks=/dev/sda/ks.cfg' or
'linux ks=/dev/sda1/ks.cfg' or 'linux
ks=ftp://what.ever.Ip.address/pub/ks.cfg' but when the installer starts
I just gen error (something) like 'null: bad address.
I've checked the RH docs and it seems that at the very least the USB

method should work.
Thanks in advance

LeeHow would you create a CentOS 7 USB installer with a data partition to store kickstart files?
We will be getting some new servers shortly and overall I’m expecting to do over 30 servers installs. What I’d really like to do is have a usb stick that I boot off of and then use kickstart to do the install.
With CentOS 7, the CentOS wiki says to use dd to copy the ISO to the usb drive e.g.
That works great, but the ISO is just over 6.5GB, I should have left over space.
Looking at fdisk, I would have guessed I could just add a partition starting at 13793280, but I’ve tried it three times and every time creating the extra partition causes the installer to error out when before creating a third partition it worked on the same system.
If I have to setup a web server to serve the kickstart files, I could probably do that but I’m not eager to go through the process that would require. I’m not sure if I could do that in our secondary site or what resistance there may be for that.
I also need to develop a disaster recovery strategy, so if I could say buy new servers, follow procedure X to create a USB stick, do the install by booting off the USB stick, then I could kill two birds with one stone.
I’m semi-resigned to have to edit the boot parameters manually for now to add the ks= parameter at least initially. Since you can use UUID, it should be possible to have a single command per type of server and I can easily provide that to the people who will rack the servers. What I’d really like to avoid though is having two USB thumb drives (one for installation media and the other for kickstart file).
Edit: I should have said that the validation the installer does originally passes, but after adding and formatting the partition it fails. I don't think that's significant as I my assumption is the partition table affects that checksum, but its possible that the partitions overlap and creating the file system is corrupting data.
Edit 2: Just in case I'm doing something wrong when creating the third partition, I thought I'd add the output of fdisk after adding the partition.

I found a great guide on how to install CentOS 7 using a USB drive and kickstart here:
I suspect that modifying the partition table of a ISO image is not easily feasible.
