Currently NixOS creates the swapfile (with the specified size) only if
it doesn't already exist. Changing the swapfile size afterwards will not
have any effect.
This commit changes that so the swapfile will be recreated whenever
swapDevices.*.size is changed (or more precisely, whenever the actual
file size differs from the configured one), allowing both growing and
shrinking the swapfile.
The service unit has "restartIfChanged = false", so we don't have to
worry about the swapfile being in use at the time this code is run (you
have to reboot for swapfile changes).
fallocate doesn't shrink files, use truncate for that. truncate can also
be used to grow files, but it creates "holes" in the file which doesn't
work with swapfiles.
':' is currently used as separator in /boot/grub/state for the list of
devices GRUB should be installed to. The problem is that ':' itself may
appear in a device path:
/dev/disk/by-id/usb-SanDisk_Cruzer_20043512300546C0B317-0:0
With such a path, NixOS will install GRUB *every* time, because it
thinks the configuration differs from the state file (due to the wrong
list split). Fix it by using ',' as separator.
For existing systems with GRUB installed on multiple devices, this
change means that GRUB will be installed one extra time.
Fixup regression introduced in commit 1bbcd91b2e
("spacefm: sudo and gksu fixes#15758 and license update").

- RPi3 successfully gets to U-Boot, but then fails to boot the kernel
due to a missing device tree file. This should get added to the 4.8
kernel release once this patch is merged: https://lkml.org/lkml/2016/6/1/841
- RPi2 is not tested, but it should successfully boot the NixOS image.
Instead of showing this output from "nixos-rebuild switch":
warning: not applying GID change of group ‘munin’
warning: not applying UID change of user ‘ntp’
print this:
warning: not applying GID change of group ‘munin’ (95 -> 102)
warning: not applying UID change of user ‘ntp’ (3 -> 179)
This makes it possible for users to take action and fixup the UIDs/GIDs
that NixOS won't touch.
Fixes issue when upgrading from very old NixOS systems that don't have
systemd-escape in $PATH:
$ sudo nixos-rebuild switch
...
building the system configuration...
updating GRUB 2 menu...
Can't exec "systemd-escape": No such file or directory at /nix/var/nix/profiles/system/bin/switch-to-configuration line 264.
Unable to escape /!
Fixes this (line wrapped):
$ gnome-control-center
[... click on the "Color" item ...]
(gnome-control-center:3977): color-cc-panel-WARNING **: \
The name org.freedesktop.ColorManager was not provided by any .service files
With this patch applied, the above warnings are not printed and the GUI
shows some devices that can be managed (my printer and display). Without
this patch the GUI is empty (non-functional).
(cups will also complain in the journal with a similar message when
doing print jobs, without this patch.)
The docstring for the `services.dbus.packages` configuration option only
mentioned one directory, but the implementation actually looked for DBus
config files in four separate places within the target packages. This
commit updates the docstring to reflect the actual implementation
behaviour.
stripHash uses a global variable to communicate it's computation
results, but it's not necessary. You can just pipe to stdout in a
subshell. A function mostly behaves like just another command.
baseHash() also introduces a suffix-stripping capability since it's
something the users of the function tend to use.
...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.
