> I'm not sure why you think that Fedora PXE installs will automatically wipe disks - they'll do whatever Kickstart tells them to do. The only thing relevant to secure boot here is that you need a signed bootloader, just like when you book off CD. 

They'll do whatever the kickstart file says - which means for any
untrusted distribution path like PXE your kickstart file had better be
signed too
