http://forums.fedoraforum.org – Hi friends, i would to know if exist one option to insert into the kickstart file for build the 64bit spin architecture , without change the repo string: Code: repo --name=fedora --mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearch to be more clear: there is a possibility to communicate to livecd-creator the new architecture without changing the variable "arch=$basearch"? man ymany thanks!
