Commit 9a629f5 "utils/docker-run: allow running with Podman" added an
option on system providing the podman command. This case is mainly
for Fedora systems.
Fedora repositories have a podman-docker package, that provides the
docker command for compatibility. See [1]. In that case, invoking
"docker" redirects to podman.
When this package is installed on a Fedora system, both the docker and
podman commands are available. Since the docker command is checked
before podman, the --userns option is not passed in that case. This
brings "permission denied" errors.
Other cases are also possible, like a host system providing the real
Docker alongside a podman installation. In such a case, to avoid
unexpected change of behavior of the docker-run script, the original
search order is preserved (search for "docker" first, then "podman").
This commit changes the way the podman user namespace mode is set.
Rather than adding the "--userns=keep-id" command line option only in
the podman case, it is globally set using the PODMAN_USERNS=keep-id
environment variable [2].
Doing so makes sure that the variable will be consumed by the "docker"
compatibility command, and just ignored by the real "docker"
implementation.

This directory contains various useful scripts and tools for working
with Buildroot. You need not add this directory in your PATH to use
any of those tools, but you may do so if you want.
brmake
a script that can be run instead of make, that prepends the date in
front of each line, redirects all of the build output to a file
("'br.log' in the current directory), and just outputs the Buildroot
messages (those lines starting with >>>) on stdout.
Do not run this script for interactive configuration (e.g. menuconfig)
or on an unconfigured directory. The output is redirected so you will see
nothing.
check-package
a script that checks the coding style across the buildroot tree. It
checks package's Config.in and .mk files, runs shellcheck for all shell
scripts, flake8 for python files, checks for typoes, etc.
It checks the .checkpackageignore file if errors should be ignored and
errors if there's a file listed that doesn't produce an error.
docker-run
a script that runs a command (like make check-package) inside the
buildroot CI docker container; pass no command to get an interactive
shell.
genrandconfig
a script that generates a random configuration, used by the autobuilders
(http://autobuild.buildroot.org). It selects a random toolchain from
support/config-fragments/autobuild and randomly selects packages to build.
get-developers
a script to return the list of people interested in a specific part
of Buildroot, so they can be Cc:ed on a mail. Accepts a patch as
input, a package name or and architecture name.
scancpan
a script to create a Buildroot package by scanning a CPAN module
description.
scanpypi
a script to create a Buildroot package by scanning a PyPI package
description.
size-stats-compare
a script to compare the rootfs size between two different Buildroot
configurations. This can be used to identify the size impact of
a specific option, of a set of specific options, or of an update
to a newer Buildroot version...
test-pkg
a script that tests a specific package against a set of various
toolchains, with the goal to detect toolchain-related dependencies
(wchar, threads...)
