No. But if I would like something to basically halt my machine on
suspicion of broken RAM, I'd like it to be something I install all by self
and not something that is forced upon me by Systemd policy. Luckily I have
Devuan.
I am not sure whether there is some kind of broken memory handling daemon
available already. However I strongly suggest finding out which RAM bars
are affected and replace them. Not sure how to do that, but I'd start with
memtest86+ which recently became available with UEFI support, in case you
use UEFI.
