Netboot Transport and PKI

On 1.5.x a single httpproto setting decides the web protocol, the HTTP→HTTPS redirect and whether iPXE is recompiled, all at once — and turning it on disables Secure Boot staging entirely. 1.6 splits those apart into separate settings, and renamed every one of them; an existing .fogsettings migrates itself on first run.

Which version am I on?

Check FOG Configuration → FOG Settings → General → FOG_VERSION in the web UI, or the version string printed at the top of installfog.sh.
