This needs a directory that's going to be present on the host operating
system across various configurations of all supported distributions,
such as the hosts running the CI, but not inside the Toolbx containers.
It looks like /etc/kernel is present on both Debian and Fedora, but
absent from the fedora-toolbox images. On a Debian 10 server, it's
owned by several packages:
$ dpkg-query --search /etc/kernel
dkms, systemd, grub2-common, initramfs-tools, apt: /etc/kernel
... while on Fedora 36 Workstation:
$ rpm --file --query /etc/kernel
systemd-udev-250.8-1.fc36.x86_64
Currently, there's no way to get assert_line to use the stderr_lines
array [1]. This is worked around by assigning stderr_lines to the
'lines' array.
