Bug ID: 1217734
           Summary: Insecure network installation instructions
           Product: Fedora Documentation
           Version: devel
         Component: install-guide
          Assignee: [e-mail]

Description of problem:

The install guide specifies to download the kernel/initrd for PXE boots over an
unencrypted connection and skips any form of verification.

Version-Release number of selected component (if applicable):
N/A

How reproducible:
100%

Steps to Reproduce:
1. Follow instructions:

https://docs.fedoraproject.org/en-US/Fedora/21/html/Installation_Guide/pxe-k...

(note the wget URLs)

Actual results:
If just a single network between my machine being booted and the Red Hat
download server is malicious, then my machine could get 0wned :( (and I would
probably be none the wiser)

Expected results:
To be able to securely install an operating system in 2015 on my new hard drive
in a single evening without crying in despair.

And to not have a deep dark fear that the instructions on the previous page
are also horribly insecure:

(I really hope those stage2 and root lines verify the image that is downloaded)
