Set up mock build environment:

$ sudo dnf install mock pykickstart
$ sudo usermod -a -G mock $(whoami)
$ mock -r ./nobara-40-x86_64.cfg --init
$ mock -r ./nobara-40-x86_64.cfg --install lorax-lmc-novirt vim-minimal pykickstart

Transfer flat kickstart file to mock build environment:

$ cp ISO-ready-flattened-kickstarts/40/*.ks /var/lib/mock/nobara-40-x86_64/root/builddir/

Enter mock environment:

$ mock -r ./nobara-40-x86_64.cfg --shell --old-chroot --enable-network
