/etc/init.d/bootmisc script from sys-apps/openrc-0.12.4 cleans /run from root partition (by using mount --bind) without checking /run is really on tmpfs, meaning it can clean used /run by mistake. Note that I did installed openrc-0.11 before (sys-apps/openrc-0.11.8) which was supposed to do some transition and still have no idea who is supposed to mount tmpfs on /run. Am I supposed to write it manually in /etc/fstab? Or is initramfs (which I'm not using) doing it? udev? pulseaudio :-)? Reproducible: Always Steps to Reproduce: 1. boot system :-) Actual Results: bootmisc will remove live /run/openrc, leading to bug #493544 Expected Results: bootmisc should either mount tmpfs on /run itself, or check it was done before cleaning /run from root partition. Note that few lines after "clean_run", there is similar line mountinfo -q -f tmpfs /var/run || cleanup_var_run_dir ... I didn't looked what the mountinfo actually does, but it feels like just the check we need.

I am unable to reproduce this. Here is a little more explanation of clean_run and why it shouldn't happen. 1. The bind mount mounts / to a temporary directory which I will call tmpdir for the sake of discussion. 2. Bind mounts are not recursive, so /tmpdir/run is not the same as /run. It is what would be under the tmpfs mounted at /run. 3. There should be nothing in /tmpdir/run/*, so that is what we remove, not /run/*, so I'm uncertain how /run/* ended up empty.
I already explained that there is no tmpfs mounted on my /run. I'm not sure why, might've been because I didn't do the transition to openrc/baselayout-2 correctly or because I have hand-compiled kernel. I'm saying that instead of assuming that the tmpfs is mounted it would be better to check before starting something so destructive.
