Using gdb from a container to debug rpm-ostree

gistfile1.txt

Start the container using at least these switches:

      (host) podman run -ti \
               --privileged \
               --pid=host \
               -v /:/host \
               --name gdb \
               --detach-keys=ctrl-t \
                 registry.fedoraproject.org/fedora:32 /bin/bash

Attach to rpm-ostree:

      (cnt) dnf install -y gdb procps-ng
      (cnt) gdb -p $(pidof rpm-ostree) \
               -ex 'set sysroot /host' \
               -ex 'directory /host/var/roothome/sync' \
               -ex 'directory /host/var/roothome/sync/libdnf/libdnf'
