Does somebody know if those are safe to delete? As far as I understand, they came from systemd, which I intend to purge in the near days.

I dont think these links are helpful for PO. I think the reason for this behavior is that he has enabled CONFIG_PSTORE and CONFIG_EFI_VARS_PSTORE (I dont recommend because it can fill the UEFI NVRAM). _________________ https://wiki.gentoo.org/wiki/User:Pietinger

Yes, I did that while I was investigating an issue with hibernate, I guess it is a few threads below. Not any more. They all had the date I did that test. But now I see they have the date of the latest reboot which is today. I also read in an issue on systemd's github that they mount it read-write either way: https://github.com/systemd/systemd/issues/2402
