Actually I think this is a good feature, but ...
+1
The feature page is wrong about "The user experience should
barely
change. This is mostly a low-level change that has little visibility
to the user."
tmpfs is different in a number of important ways:
- it's very limited in space compared to a real disk
- it doesn't support O_DIRECT
- it doesn't support user extended attrs; and not very old kernels
didn't support any xattrs at all, meaning things like SELinux
labels don't work
- quota, the generic tmpfs problem...
