In case of a power loss shortly after first boot,
the host keys gernerated by ssh-keygen could exist
in the file system but have zero size, preventing
sshd from starting up.
This commit changes the behaviour to generate host
keys if the file either does not exist or has zero
size, fixing the problem on the next boot.
Thanks to @SuperSandro2000 for figuring this out.
A few minor changes to get #119638 - nextcloud: add option to set
datadir and extensions - ready:
* `cfg.datadir` now gets `cfg.home` as default to make the type
non-nullable.
* Enhanced the `basic` test to check the behavior with a custom datadir
that's not `/var/lib/nextcloud`.
* Fix hashes for apps in option example.
* Simplify if/else for `appstoreenable` in override config.
* Simplify a few `mapAttrsToList`-expressions in
`nextcloud-setup.service`.
Note the appstoreEnable which will prevent nextcloud form updating
nix-managed apps. This is needed because nextcloud will store an other
version of the app in /var/lib/nextcloud/store-apps and it will
no longer be manageable.
The multipath-tools package had existed in Nixpkgs for some time but
without a nixos module to configure/drive it. This module provides
attributes to drive the majority of multipath configuration options
and is being successfully used in stage-1 and stage-2 boot to mount
/nix from a multipath-serviced iSCSI volume.
Credit goes to @grahamc for early contributions to the module and
authoring the NixOS module test.
Don't worry, it's is true by default. But I think this is important to
have because NixOS indeed shouldn't need Nix at run time when the
installation is not being modified, and now we can verify that.
NixOS images that cannot "self-modify" are a legitamate
use-case that this supports more minimally. One should be able to e.g. do a
sshfs mount and use `nixos-install` to modify them remotely, or just
discard them and build fresh ones if they are run VMs or something.
The next step would be to make generations optional, allowing just
baking `/etc` and friends rather than using activation scripts. But
that's more involved so I'm leaving it out.
The `$(</path/to/file)`-expansion appears verbatim in the cmdline of
`nextcloud-occ` which means that an unprivileged user could find
sensitive values (i.e. admin password & database password) by monitoring
`/proc/<pid>/cmdline`.
Now, these values don't appear in a command line anymore, but will be
passed as environment variables to `nextcloud-occ`.
* Linkify documentation about objectstore-feature rather than only
mentioning it.
* Use `<literal>` where it makes sense.
* Remove unnecessary `Whether to load` from `enableImagemagick` because
`mkEnableOption` already prepends `Whether to enable` to the given
description.
NixOS should be able to support the Nintendo Switch Pro controller for
steam and non-steam at the same time. Currently there are two mutually
exclusive ways to support the Pro Controller: Steam and `hid-nintendo`.
Unfortunately these don't work together, but there's a workaround in
newer versions of `joycond` (described [here](https://wiki.archlinux.org/title/Gamepad#Using_hid-nintendo_pro_controller_with_Steam_Games_(with_joycond))). To use this
workaround `hid-nintendo` and `joycond` need to be updated, and the
systemd and udev configuration needs to be made available in NixOS.
