E.g.
The unique option `fileSystems./.device' is defined multiple times, in `/etc/nixos/configuration.nix' and `/etc/nixos/foo.nix'.
This requires passing file/value tuples to the merge functions.
There's a zlib version included with milkytracker,
but there's no makefiles for it. I've only included
the header here, but it fails at link-time with
several 'undefined reference' errors, which simply
means it can't find the definitions, e.g. compiled
zlib.
There's bug reports on other package systems although
unfortunately still unresolved.

An annoying and dangerous property of "types.string" is that it merges
multiple definitions by concatenating them, which almost never
produces a sensible result. (Those options for which it does make
sense typically should use "types.lines" instead, and things only work
because the option definitions already end in a newline.) Of course,
you can use "types.uniq types.string", but that's rather verbose, and
inconsistent with other basic types like "types.int".
Changing the behaviour of "types.string" to be unique by default is
not an option, given the large number of options that use it. So
instead, we now have "types.str", which is equivalent to "types.uniq
types.string".
They fail randomly due to a hard-coded 30-second timeout in udev
waiting for /dev/sda1 to appear:
systemd-udevd[1151]: worker [1168] /devices/pci0000:00/0000:00:04.0/host2/target2:0:0/2:0:0:0/block/sda/sda1 timeout; kill it
systemd-udevd[1151]: seq 1059 '/devices/pci0000:00/0000:00:04.0/host2/target2:0:0/2:0:0:0/block/sda/sda1' killed
Hopefully we can use virtio in the future for the EFI tests.

Now that overriding fileSystems in qemu-vm.nix works again, it's
important that the VM tests that add additional file systems use the
same override priority. Instead of using the same magic constant
everywhere, they can now use mkVMOverride.
