ass='msg-avail'>...This avoids problems where 'isatty?' return #t but 'ttyname' fails with ENOTTY or such. * gnu/build/linux-container.scm (mount-file-systems): Remove call of 'isatty?'. Directly call 'ttyname' and catch 'system-error'. Ludovic Courtès 2016-11-10container: Pass a list of <file-system> objects as things to mount....* gnu/build/linux-container.scm (mount-file-systems): 'mounts' is now a list of <file-system> objects instead of a list of lists ("specs"). Add call to 'file-system->spec' as the argument to 'mount-file-system'. (run-container, call-with-container): Adjust docstring accordingly. * gnu/system/file-systems.scm (spec->file-system): New procedure. * gnu/system/linux-container.scm (container-script)[script]: Call 'spec->file-system' inside gexp. * guix/scripts/environment.scm (launch-environment/container): Remove call to 'file-system->spec'. * tests/containers.scm ("call-with-container, mnt namespace") ("call-with-container, mnt namespace, wrong bind mount"): Pass a list of <file-system> objects. Ludovic Courtès 2016-10-19container: Allow 'container-excursion' to the same namespaces....Before that, 'container-excursion' would call 'setns' even when the target namespace is the one the caller is already in, which would fail. * gnu/build/linux-container.scm (container-excursion): Introduce 'source' and 'target'. Compare the result of 'readlink' on these instead of comparing file descriptors to decide whether to call 'setns'. * tests/containers.scm ("container-excursion, same namespace"): New test. Ludovic Courtès 2016-05-31container: Gracefully report mount errors in the child process....Fixes <http://bugs.gnu.org/23306>. * gnu/build/linux-container.scm (run-container): Use 'socketpair' instead of 'pipe'. Rename 'in' to 'child' and 'out' to 'parent'. Send a 'ready message or an exception argument list from the child to the parent; adjust the parent accordingly. * tests/containers.scm ("call-with-container, mnt namespace, wrong bind mount"): New test. * tests/guix-environment-container.sh: Add test with --expose=/does-not-exist. Ludovic Courtès 2016-05-31container: Gracefully handle failure to set up user namespaces....* gnu/build/linux-container.scm (run-container): Exit when the parent process doesn't say 'ready.
