I used this live image CentOS-7.0-1406-x86_64-GnomeLive.iso, CentOS-7.0-1406-x86_64-KdeLive.iso to boot from USB to testing some servers. However, I'd would like to add some lib such as "ndctl" on this live image.

Please kindly advise me how to build the live image which include "ndctl" at boot USB up without download it everytime after boot.

Thanks a lot.

    Your best bet is to just install CentOS 7 to the USB itself, install what you need, and then boot from it. – Nasir Riley Nov 1 '18 at 16:00

  • Customized iso is a large topic. Use kickstart and post if you have a problem devopsmates.com/make-custom-centos-7-rhel-7-cd-kicktart-file – Panther Nov 1 '18 at 16:38
  • @Fabby no it is a work around. The op is asking to customize the iso and kickstart is the easy method – Panther Nov 1 '18 at 16:40

Your best bet is to just install CentOS 7 to another USB stick, install what you need, and then boot from it.
