Although you can choose this in the installer, isnt the provided values supposed to be the default? I tired the following inst.repo=hd:/dev/sdb1:/repo Result: /dev/sdb1 is not mounted. inst.repo=nfs:[fc00::6009]:/home/auser/repo Result: NFS is not mounted even the correct ip is set by passing ip= parameters. Of course I tested the NFS share using CentOS itself. Thanks for any assistance!
