https://bugzilla.kernel.org/show_bug.cgi?id=217547 Bug ID: 217547 Summary: The shell example in time_namespaces doesn't behave as documented Product: Documentation Version: unspecified Hardware: All OS: Linux Status: NEW Severity: normal Priority: P3 Component: man-pages Assignee: documentation_man-pages@xxxxxxxxxxxxxxxxxxxx Reporter: goeran@xxxxxxxxxxx Regression: No Trying the shell example in the manual page for time_namespaces(7) does not behave for me the way the manual page says it should. From what I can tell, it appears that the new shell ITSELF immediately enters the new namespace, rather than allowing for children to enter. This makes it impossible to write anything to the time_for_children file. Using the --boottime flag to unshare gives the expected behavior. Does an exec() trigger entering the new time namespace nowadays? This was tested on a Fedora 38 system running kernel 6.2.14-300.fc38.
