systemd gets stuck because it’s trying to mount two separate partitions to the same mount point

Uh… Sounds like it’s not really systemd’s fault, your setup is just terrible.

I’ve tried fixing it, but all I did was break it more.

If you’re unable to fix it, maybe get somebody else? Like, this doesn’t sound like it’s an unfixable issue…

Sorry to be that guy, but this sounds like a cybersecurity nightmare. While everybody was busy to come up with schemes that make absolutely sure that only trusted sources can update a system to avoid having malicious players push their code to users, this one just takes any rando’s pile of whatever and injects it straight into the system’s core? Like, that doesn’t sound like a good idea.

It’s amazing

It sometimes makes up things
