I see the use case but I don't see that we need new functionality inside agetty because distros could either use agetty --issue-file /run/generated-issues or ln -sf /run/generated-issues /etc/issues Speaking as an admin I really hate that distros nowadays introduce more and more techniques to let 3rd parties change global setup within /usr (where I don't see it) instead of using /etc which I track and review using git. I fully understand that this makes it much easier for the distro developers. But the resulting systems are more difficult and complex to understand and to debug for the admins. BTW looking over /etc we could actually use the "agetty argument" to introduce the "/usr-/run/-/etc merge technique" also for any other programs too. Why not moving the distro's default /etc/hosts, /etc/services, /etc/ntp.conf, /etc/cron.d, *everything* to /usr? No more noise in /etc on upgrade/install... Will admins be more happy when all installations and distros finally have the same empty /etc by default but still being completely differently configured *somewere* in /run and /usr? cu, Rudi -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
