proper hostapd dependencies
When enabling wacom put xsetwacom in PATH.

I know that gnome/kde may have their own way to configure wacom tablets
s/boot.grubDevice/boot.loader.grub.device/ to shut down warnings
add wantedBy network.target so that hostapd starts by default

Static nameservers should have precedence
systemd: add "requiredBy" option.

"require" is a stronger version of "want",
and just like wantedBy allows you to specify this relation in reverse,
requiredBy does the same.

It may seem pointless to be able to specify these stronger relations in
reverse, because if something is really required, you would expect the
other unit to specify this himself.

However, this is still useful for virtual/automatic units (like
devices) that are created by systemd on demand and hence have no unit
file you can alter.
virtual network interfaces: make systemd aware of the relation between device and service

If I want to bring down tap0.service (or systemd wants to do this
during a configuration-change which changes the path to tunctl),
openvpn (or other services using tap0) need to be brought down as
well, otherwise tunctl -d is not able to remove the tap0 device,
leaving it in a failed (but "up") state.
cron: set TZDIR so cron is able to find the TZ

Don't set $TZ

We don't need to set $TZ, because we have /etc/localtime.  In fact,
setting $TZ without $TZDIR doesn't work anymore since Glibc no longer
contains zone info.
Create a /etc/zoneinfo symlink and use it in $TZDIR

Setting $TZDIR to ${pkgs.tzdata}/share/zoneinfo can cause logged-in
sessions to refer to a garbage-collected zoneinfo directory.  So use
/etc/zoneinfo instead.

nixos-install: fix error message consistency

The test is for path A but the error message says path B. Fix it.
