These tests assume that the group and user information on the host operating system can be provided by different plugins for the GNU Name Service Switch (or NSS) functionality of the GNU C Library. eg., on enterprise FreeIPA set-ups. However, it's expected that everything inside the Toolbx container will be provided by /etc/group, /etc/passwd, /etc/shadow, etc.. While /etc/group and /etc/passwd can be read by any user, /etc/shadow can only be read by root. However, it's awkward to use sudo(8) in the test cases involving /etc/shadow, because they ensure that root and $USER don't need passwords to authenticate inside the container, and sudo(8) itself depends on that. If sudo(8) is used, the test suite can behave unexpectedly if Toolbx didn't set up the container correctly. eg., it can get blocked waiting for a password. Hence, 'podman unshare' is used instead to enter the container's initial user namespace, where $USER from the host appears as root. This is sufficient because the test cases only need to read /etc/shadow inside the Toolbx container. containers#1355

The tests run on Fedora Rawhide nodes are failing because of the same reasons as in #1344 and #1331 , and the root cause appears to be rsync: https://bugzilla.redhat.com/show_bug.cgi?id=2229654 So, I am going to temporarily ignore these test failures on Fedora Rawhide. |
