Until now nixos only delivered the latest zfs release. This release is often not
compatible with the latest mainline kernel. Therefor an unstable variant is
added, which might be based on testing releases or git revisions.
fixes#21359
/etc/hostname is the file used by hostnamectl(1) and the
org.freedesktop.hostname1 dbus service (both provided by systemd) to get
the "static hostname". Better provide it so that users of those
tools/services get a proper hostname.
An example of an issue created by the lack of /etc/hostname is that the
bluetooth stack on NixOS identifies itself to peers as "BlueZ $VERSION"
instead of the hostname.

Changes v1 -> v2:
* ensure /etc/hostname ends with a newline
Now the tracking works with aggregated devices on aggregated devices.
So container with physical device where the device is put in a bond
which is the basis for a bridge is now handled correctly.
Test that adding physical devices to containers works, find that network setup
then doesn't work because there is no udev in the container to tell systemd
that the device is present.
Fixed by not depending on the device in the container.
Activate the new container test for release
Bonds, bridges and other network devices need the underlying not as
dependency when used inside the container. Because the device is already
there.
But the address configuration needs the aggregated device itself.
Using types.str doesn't work if you want to mkBefore/mkAfter across
different module definitions, because it only allows for one definition
for the same priority.
This is especially useful if you deploy Hetzner machines via NixOps,
because the physical specification already defines localCommands.

See #18319 for details. Starting network-online.target manually does not
work as it hangs indefinitely.
Additionally, don't treat avahi and dhcpcd special and sync their systemd units
with the respective upstream suggestion.
Systemd upstream provides targets for networking. This also includes a target network-online.target.
In this PR I remove / replace most occurrences since some of them were even wrong and could delay startup.
A new internal config option `fileSystems.<name>.early` is added to indicate
that the filesystem needs to be loaded very early (i.e. in initrd). They are
transformed to a shell script in `system.build.earlyMountScript` with calls to
an undefined `specialMount` function, which is expected to be caller-specific.
This option is used by stage-1, stage-2 and activation script to set up and
remount those filesystems. Options for them are updated according to systemd
defaults.
Also add required systemd services for starting/stopping mdmon.
Closes#13447.
abbradar: fixed `mdadmShutdown` service name according to de facto conventions.
Allow usage of list of strings instead of a comma-separated string
for filesystem options. Deprecate the comma-separated string style
with a warning message; convert this to a hard error after 16.09.
15.09 was just released, so this provides a deprecation period during
the 16.03 release.

- add missing types in module definitions
- add missing 'defaultText' in module definitions
- wrap example with 'literalExample' where necessary in module definitions
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
Configuration option for setting up virtual WLAN interfaces.
If the hardware NIC supports it, then multiple virtual WLAN interfaces can be
configured through the options of the new 'networking.wlanInterfaces' module.
For example, the following configuration transforms the device with the persistent
udev name 'wlp6s0' into a managed and a ad hoc device with the device names
'wlan-managed0' and 'wlan-adhoc0', respectively:
networking.wlanInterfaces = {
"wlan-managed0" = {
type = "managed";
device = "wlp6s0";
};
"wlan-adhoc0" = {
type = "ibss";
device = "wlp6s0";
};
};
Internally, a udev rule is created that matches wlp6s0 and runs a script which adds
the missing virtual interfaces and re-configures the wlp6s0 interface accordingly.
Once the new interfaces are created by the Linux kernel, the configuration of the
interfaces is managed by udev and systemd in the usual way.
The default options for all file systems currently are
"defaults.relatime", which works well on file systems which support the
relatime option.
Unfortunately, this is not the case for the VirtualBox shared folder
filesystem, so until now, you need to set something like:
fileSystems."/foo" = {
device = "foo";
fsType = "vboxsf";
options = "defaults";
};
Otherwise mounting the file system would fail.
Now, we provide only the "defaults" option to the "vboxsf" file system,
so something like this is enough:
fileSystems."/foo" = {
device = "foo";
fsType = "vboxsf";
};
An alternative to that could be to document that you need to set default
options, but we really should do what users expect instead of forcing
them to look up the documentation as to why this has failed.

If you power off your machine frequently, you could miss the execution
of some snapshots.
This is more troublesome the more infrequently the snapshots are
triggered. For example, monthly snapshots only execute at exactly
midnight on the first day of the month. If you only have your
machine powered on at that time with probability 50%, then half the
snapshots won't be triggered.
This means that if you wanted to keep 3 monthly snapshots, then instead
of keeping 3 months' worth of snapshotted data as you expected, you would
end up with snapshots spanning back 6 months.
Adding the "Persistent = yes" option to auto-snapshot timer units makes
a missed snapshot execute when booting up the machine.
Otherwise, in certain cases, snapshots of infrequently-modified
filesystems can be kept for a much longer time than the user would
normally expect, and cause a large amount of extra disk space to be
consumed.
Also added flag to snapshot filesystems in parallel by default.
I've also added a configuration option for zfs-auto-snapshot flags, so
that the user can override them.
For example, the user may want to append --utc to the list of default
options, so that the snapshot names don't cause name conflicts or
apparent time reversals due to daylight savings or timezone changes.
