Neither does this (which apps needs O_DIRECT on /tmp ? ).
qemu and libguestfs as it turned out. It was one of the things we had to fix when we first ported to Debian.
It's not completely unusual that an application should want to directly access a cache file, bypassing the page cache, nor that it would want to store such a file in /tmp. My point was that these things will be discovered when we test every application.
- 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
Huh? Why would you run a "very old kernel" on fedora?
It's not unknown that people use different kernels from the ones supplied. I said "not very old", by which I meant >= 12 months old.
