Now that the kernel has CLONE_NEWNS, it's possible to mount proc "privately" just for a specific process tree. It meshes nicely with CLONE_NEWPID. Previously if you mounted proc in a chroot, it cluttered the mount list and leaked information about outside the root. With modern clone/unshare, that's no longer a concern, so there's much less reason to use "bare" chroots. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
