Howto create installation image.

[Madper]

Hi Artem,


Did you use your own tmpl file? (e.g.: tweaked the packages that should be installed...)
It seems requires dnf in the repo when you build the iso on fedora. However it do seems that I can't find dnf in centos' repo.

Hi,

I successfully used lorax.

I used it in Fedora, but you can build CentOS images in Fedora if you
point loarax to Centos repos.

I used something like this:

lorax -p CentOS -v 7 -r 7 -s URL1 -s URL2 results

where
* URL1 - the base CentOS7 repo
* URL2 - the updates repo

HTH,
Artem.
