qemu: Apply interim fix for overlayfs + O_NOATIME Our VM tests and everything related to our virtualisation infrastructure is currently broken if used with kernel 4.19 or later. The reason for this is that since 4.19, overlayfs uses the O_NOATIME flag when opening files in lowerdir and this doesn't play nice with the way we pass the Nix store to our QEMU guests. On a NixOS system, paths in the Nix store are typically owned by root but the QEMU process is usually run by an ordinary user. Using O_NOATIME on a file where you're not the owner (or superuser) will return with EPERM (Operation not permitted). This is exactly what happens in our VM tests, because we're using overlayfs in the guests to allow writes to the store. Another implication of this is that the default kernel version for NixOS 19.03 has been reverted to Linux 4.14. Work on getting this upstream is still ongoing and the patch I posted previously was incomplete, needs rework and also some more review from upstream maintainers - in summary: This will take a while. So instead of rushing in a kernel patch to nixpkgs, which will affect all users of overlayfs, not just NixOS VM tests, I opted to patch QEMU for now to ignore the O_NOATIME flag in 9p. I think this is also the least impacting change, because even if you care about whether access times are written or not, you get the same behaviour as with Linux 4.19 in conjunction with QEMU.
