I've observed that the "build kernel on a separate node" tasks are
now failing when my controller is Fedora 42 and the selected target
nodes are running Debian 11. Daniel has confirmed this:

We believe that commit 75f870367e16 ("bootlinux: Update grub on
Debian after installing debs") is the culprit. Revert that commit
so we can find a fix that doesn't break the bootlinux_builder
tasks.

Building bindeb-pkg requires the rsync package on some Debian systems. Enabling BTF (as the Debian 11 kernel config does) requires pahole. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
This task got lost somewhere. Without artifact_paths, one or more subsequent tasks fail with "undefined variable" when building the Linux kernel on a separate builder node. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
packages.yml handles kernel RPM installation already. Now add similar support for installing kernel debs on Debian systems. Generated-by: Claude AI Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
Unlike the kernel RPMs built by bin-rpmpkg, the Debian debs do not update the grub configuration. That has to be handled explicitly. Generated-by: Claude AI Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
Commit 434df33 ("workflows: linux: remove explicit inventory in ansible wrappers") added "--limit 'baseline:dev' to the bootlinux Makefile invocation to exclude localhost from the list of hosts that get a kernel update. This, however, excludes the nfsd host. When it is part of a test workflow, NFSD needs to get the test kernel too. I tried adding nfsd to [baseline], but then "make nfstest" set up the test programs on the nfsd host as well as the clients.

When running "make pynfs" in the current directory, I get to the "Install pynfs build dependencies" task, which fails with the message "No package matching 'python3-standard-xdrlib' is available". The test system is running Debian 11. Python 3.13 removed xdrlib (PEP 594), and we recently adjusted install-deps/redhat/main.yml to accommodate that. I found that the xdrlib module is already part of Python 3.9's standard library on Debian 11. The package python3-standard-xdrlib doesn't exist on Debian 11 because xdrlib is included by default. Remove the python3-standard-xdrlib package and adopt the solution used by install-deps/redhat/main.yml, which is to pull in xdrlib3 when xdrlib is not included in the standard Python library (this should be only on Debian 13).

I finally have a need to use Debian instead of a Red Hat-based OS on my test runners. This means that the bootlinux_builder implementation I did for RHEL/Fedora needs to be completed so that Debian works too. This series does that and throws in a few fixes for running NFS-related workflows on Debian 11.
