Nothing is currently mounting the posix message queue fs. I've added the following in /etc/init.d/devfs to the list of dev related fs to mount: "mqueue /dev/mqueue 0755 ,defaults none" \ seems to work well enough, but I'm not sure what options and DAC settings should be the default for it. Reproducible: Always
This is fixed in commit f30eec0 which will be part of openrc-0.12. Thanks for the report.
