At least with the root partition being on LVM, the lvm openrc service won’t complete stopping, if udev was stopped before it. This is a race condition. Steps to reproduce: 1. Shutdown with a root partition on LVM. Actual results: sysfs waits indefinitely for lvm to stop. After the timeout openrc hangs forever. Magic sysrq is a workaround, but the journal of your root partition has to be restored on next reboot. Expected results: lvm stops always. Reproducible: often Portage 2.3.62 (python 3.6.5-final-0, default/linux/amd64/17.0/hardened, gcc-8.2.0, glibc-2.28-r6, 4.19.27-gentoo-r1 x86_64)
