The old boot.spl.hostid option was not working correctly due to an
upstream bug.
Instead, now we will create the /etc/hostid file so that all applications
(including the ZFS kernel modules, ZFS user-space applications and other
unrelated programs) pick-up the same system-wide host id. Note that glibc
(and by extension, the `hostid` program) also respect the host id configured in
/etc/hostid, if it exists.
The hostid option is now mandatory when using ZFS because otherwise, ZFS will
require you to force-import your ZFS pools if you want to use them, which is
undesirable because it disables some of the checks that ZFS does to make sure it
is safe to import a ZFS pool.
The /etc/hostid file must also exist when booting the initrd, before the SPL
kernel module is loaded, so that ZFS picks up the hostid correctly.
The complexity in creating the /etc/hostid file is due to having to
write the host ID as a 32-bit binary value, taking into account the
endianness of the machine, while using only shell commands and/or simple
utilities (to avoid exploding the size of the initrd).

It turns out that the upstream systemd services that import ZFS pools contain
serious bugs. The first major problem is that importing pools fails if there
are no pools to import. The second major problem is that if a pool ends up in
/etc/zfs/zpool.cache but it disappears from the system (e.g. if you
reboot but during the reboot you unplug your ZFS-formatted USB pen drive),
then the import service will always fail and it will be impossible to get rid
of the pool from the cache (unless you manually delete the cache).
Also, the upstream service would always import all available ZFS pools every
boot, which may not be what is desired in some cases.
This commit will solve these problems in the following ways:
1. Ignore /etc/zfs/zpool.cache. This seems to be a major source of
issues, and also does not play well with NixOS's philosophy of
reproducible configurations. Instead, on every boot NixOS will try to import
the set of pools that are specified in its configuration. This is also the
direction that upstream is moving towards.
2. Instead of trying to import all ZFS pools, only import those that are
actually necessary. NixOS will automatically determine these from the
config.fileSystems.* option. Also, the user can import any additional
pools every boot by adding them to the config.boot.zfs.extraPools
option, but this is only necessary if their filesystems are not
specified in config.fileSystems.*.
3. Added options to configure if ZFS should force-import ZFS pools. This may
currently be necessary, especially if your pools have not been correctly
imported with a proper host id configuration (which is probably true for 99% of
current NixOS ZFS users). Once host id configuration becomes mandatory when
using ZFS in NixOS and we are sure that most users have updated their
configurations and rebooted at least once, we should disable force-import by
default. Probably, this shouldn't be done before the next stable release.
WARNING: This commit may change the order in which your non-ZFS vs ZFS
filesystems are mounted. To avoid this problem (now or in the future)
it is recommended that you set the 'mountpoint' property of your ZFS
filesystems to 'legacy', and that you manage them using
config.fileSystems, just like any other non-ZFS filesystem is usually
managed in NixOS.

Also remove custom zfs services from NixOS. This makes NixOS more aligned with
upstream.
More importantly, it prepares the way for NixOS to use ZED (the ZFS event
daemon). This service will automatically be enabled but it is not possible to
configure it via configuration.nix yet.

I'm not using JFS, but this is to mainly make jfsutils available if you
have defined a JFS filesystem in your configuration.

3.16.0 introduced a regression where vlan and veth devices could not be
created due to a check in the code for existing devices. This applies
the upstream patch which fixes the issue.
Additionally, this corrects the nixos network-interfaces task which now
needs to specify the name parameter when adding links.

Within the module it's referenced with an uppercase "P" and ipv6Address
also begins with an uppercase "A" after the "6", so let's make it
consistent.

nixos/network-interfaces: Sanitize sys-subsystem device names
|
| | |
| |
| |
| |
| |
| |

Currently, nixos will allow for interface names with special characters
such as the hyphen to be used. This presents a problem when using
systemd device names as the namespace paths are separated using hyphens.
Within systemd, if a device name has a hyphen it should be replaced with
the escape sequence \x2d.
This patch sanitizes all interface names before they are used in a
systemd device string.

Currently, device units are named directly after the name the user
specifies for the device. A bridge device named lan will be defined
within lan.service. This becomes a problem if you want your interface
named nginx but also want to run the nginx service.
This patch fixes the issue by appending netdev to all virtually created
network device units. Therefore, the lan bridge -> lan-netdev.service.
This naming convention is used for all types of network devices in order
to ensure that all network devices are unique.
