...by adding system-config-printer to services.dbus.packages (if
services.printing.enable is true).
Without this patch, trying to add a printer will result in a little dialog
saying "Failed to add new printer" and gnome-control-center will print this to
the terminal (line wrapped):
(gnome-control-center:3546): printers-cc-panel-WARNING **: \
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: \
The name org.fedoraproject.Config.Printing was not provided by any .service files
system-config-printer supplies the "org.fedoraproject.Config.Printing" dbus
service, thus fixing the problem.
wpa_supplicant fails to start if the wireless interfaces aren't ready yet,
so we need to add a system ordering directive here to start wpa_supplicant
after the interfaces are ready. Note that Requires= is not enough since
it does not imply ordering.
This GID was used to exempt users from Grsecurity's
`/proc` restrictions; we now prefer to rely on
`security.hideProcessInformation`, which uses the `proc` group
for this purpose. That leaves no use for the grsecurity GID.
More generally, having only a single GID to, presumably, serve as the
default for all of grsecurity's GID based exemption/resriction schemes
would be problematic in any event, so if we decide to enable those
grsecurity features in the future, more specific GIDs should be added.
The new module is specifically adapted to the NixOS Grsecurity/PaX
kernel. The module declares the required kernel configurations and
so *should* be somewhat compatible with custom Grsecurity kernels.
The module exposes only a limited number of options, minimising the need
for user intervention beyond enabling the module. For experts,
Grsecurity/PaX behavior may be configured via `boot.kernelParams` and
`boot.kernel.sysctl`.
The module assumes the user knows what she's doing (esp. if she decides
to modify configuration values not directly exposed by the module).
Administration of Grsecurity's role based access control system is yet
to be implemented.
We need to use wrapped modprobe, so that it finds the right
modules. Docker needs modprobe to load overlay kernel module
for example.
This fixes an an error starting docker if the booted system's kernel
version is different from the /run/current-system profile's one.
