RE: [SCIENTIFIC-LINUX-USERS] Create bootable ISO that can be copied to a USB key
Hi Pat Thanks for the reply I make a copy of the files from the SL-7.2-DVD-x86_64-2016-01-26.iso in a directory. I delete the packages I don't want. I copy our application software and kickstart file into the directory. I modify isolinux/isolinux.cfg to use the kickstart file. I use mkisofs to create the new ISO mkisofs -U -J -R -v -T -V PCS -o ../R20.001.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table . I burn a DVD from the new ISO which I can boot from and do the install. When I use dd to create a USB key from the ISO and try to boot from USB key, it does not boot. I have tried adding the "-eltorito-alt-boot -e images/efiboot.img -no-emul-boot" options to the mkisofs command with no success.

RE: create repodata for a custom install DVD
I will take a look at this script Thanks Mark Bill -Original Message- From: stod...@pelletron.com [mailto:stod...@pelletron.com] Sent: Friday, October 07, 2016 1:27 PM To: EXT-Askew, R W <r.w.as...@boeing.com>; scientific-linux-us...@listserv.fnal.gov Subject: Re: create repodata for a custom install DVD On 10/07/2016 01:04 PM, Bill Askew wrote: > I have been searching for a howTo that provides the steps required to create > the repodata on an install DVD. > I am using the SL 7.2 install DVD as a baseline and removing the unneeded > packages then am using a kickstart file to do the install. > This works fine without updating the repodata however if I want to add > packages or replace packages with new packages I believe I would need to > rebuild the repodata the match the new packages. > Thanks > I have a modified version, but this is what Pat sent me a few months ago (written by Connie). It is a good starting point for rolling your own. The approach I took was to put my additional packages either using the context scheme SL proposes or just another directory off the DVD root. Depending on what you decide to do, you will want to grab a copy of the original comps.xml and make any additional modifications to it. Then, from what will be the DVD root, run 'createrepo -g .' This will find and build a repo from all rpms found in subdirectories. I also have some scripts to inject custom bootloader configs and kickstart options if you are interested. Hope that helps. -Mark
