XFS is the default filesystem for RHE, and while I believe that /tmp is a tmpfs on RHE and should therefore be safe, it is my understanding that /var/tmp needs to be accessible on boot and is therefore typically on the root FS. EDIT: Can confirm for the RHE server I have access to, that this is the case

I’m seriously behind times because I’m reading RHEL switched to XFS as a default in 2013 and SUSE did that even earlier :o

I don’t even need an LLM to be confidently wrong, sorry.

Can all be separate partitions on an Enterprise Linux system. Cisa guidelines recommend some and additional mount configs since they have different roles

Those can all be separate partitions on any Linux system. But defaults matter, and if the defaults are insecure then you can expect most systems to be insecure
