At the end of the update, when it shows what is happening, I saw an error about not being able to run systemctl. I saved the install output if it is useful. But as far as I can tell the system is still working. I use a custom kernel if that matters (I don't think it does) and OpenRC. I know systemctl is a systemd tool so it seems like the problem is OpenRC. Am I wrong to post here about this issue? Only trying to offer this up for your information.
Oh, I have not rebooted yet, I thought I would post this first then try a reboot later.
