"koji download-build" is a wrong tool to download artifacts being
tested. They are freshly scratch-built and hosted in a local repo
called "test-artifacts" unknown to koji. Using "dnf download"
directly and limited to that specific repo is a correct way to
reach them.
I'm adding a fallback using the repo's local files just in case
"dnf" suffers some temporary hiccup.
Work around #1960792 (a coreutils bug). While the systems running
Fedora CI are still affected, the fix is already in the update
repos. Using "dnf update coreutils" should be enough to make our
test pass.
The kernel rebuild test has been broken since the beginning and is
hard to debug due to CI's limitations when dealing with larger logs.
Fortunately, a better replacement has been introduced by mcermak
in commits 044ff51 and 49b89d9 that renders the broken test case
pointless.
The only present test case rebuilt, installed and booted the kernel.
Now let's make the install and boot steps optional, just on explicit
request. Skipping these steps will be the default behaviour, at least
for now.
You can override the default by setting variable "JUST_BUILD" in the
environment the test runs in. The variable defaults to "yes" which
means the test will just build the kernel. If you use JUST_BUILD=no
(or JUST_BUILD=false or JUST_BUILD=0) then the test will not only
build but install and boot the kernel, too.
Note that the acceptable values of JUST_BUILD are case insensitive.
* Remove code related to RHEL versions and not interesting in Fedora.
* Remove or simplify some architecture-specific code because Fedora CI
aims at x86_64 only.
* Remove some older and commented out experiments.
Sanity/rebuild-kernel-and-reboot is imported from RHEL's
tests/binutils/Sanity/rebuild-kernel-and-reboot (as of commit c5bc77c).
It needs some adaptations first before running in Fedora.
