Comment 4 for bug 833994

We've been talking about this today. The question of certificates is a rather vexed one: we'd have to put the whole bulk of ca-certificates into the installer initrd, and furthermore many of the sites in question are going to be self-signed ones that somebody ran up locally so there would need to be a way to get certificates into the installer initrd. Furthermore, if you're PXE-booting the installer, anyone can already ARP-spoof you and substitute an installer initrd with the certificate of their choice. For lots of work, you gain not very much real security!

The installation guide does currently document that crypted passwords should be an MD5 hash, but as far as I can see there's no actual requirement for this, and a SHA-512 hash should work perfectly well. Have you tried this? Would this be sufficient to meet your compliance requirements?
