I am preparing to implement a filesystem in FUSE. Implementing only one mode would be easier. Relatime is the default behavior of all kernel implemented filesystems. Is strictatime behavior still necessary to be implemented?
Is there any existing software that relies on strictatime behaviour?
What I suspect is NOT broken:
- Ubuntu removes files from /tmp on reboot, and only if file is older than a specified number of days, as answered in this question. Smallest threshold seems to be 1 day, which is fine for (24 hour) relatime.
