Package Signature Checking During Installation
Summary
One long-standing problem in Fedora is that we don't check package signatures during installation. This has been a persistent issue since the very beginning of Fedora (and even in Red Hat Linux before it.) The reason for this has always been that there's no way to form any root of trust for the signatures in the repositories, and thus no reason they wouldn't have been modified along with whatever package would need to be re-signed after tampering.
Following the implementation of Features/SecureBoot, we can extend the Secure Boot keys as a root of trust provided by the hardware against which we can verify a signature on our key files, thus guaranteeing that they're from the same source as the boot media.

| Sub-task | Percent Complete | Owner | Notes |
| peverify | 50 | pjones | need to finish it. |
| fedora-release | 0 | pjones | 2 things here - 1) must be moved to "secure-boot" koji channel, 2) must be modified to provide a signed set of keys |
| anaconda | 0 | pjones | needs to detect that we're in a secure-boot environment and, if so, enforce signature checking on keys and packages. |
Benefit to Fedora
Allows verification of packages during installation.
Scope
See the table at https://fedoraproject.org/wiki/Features/PackageSignatureCheckingDuringInstall#Current_status
Test Plan
UEFI-capable systems with Secure Boot features are available from most vendors.
The test methodology is simple - enable secure boot, create a repo with an unsigned package in it, do an install that includes that package. Installation should fail.
User Experience
Significantly similar to that of today in most cases.
Dependencies
- peverify being trusted is probably dependent on vgoyal's work for kexec+secureboot.
- "repo" in kickstart (pykickstart, anaconda) may change to specify an enforcement policy.
- There may be additional work needed to add enforcement policy on a per-repo basis to repomd.xml.
Contingency Plan
- Bump this to a later release.

Release Notes
Probably should write one, yeah.
