Follow-up to #269551
Avoid creating a new instance of nixpkgs to access two variables.
`pkgs.pkgsi686Linux` was being accessed whenever the feature is being
used or not.
A second instance of nixpkgs is being created in
`nixos/modules/config/stub-ld.nix` and can be disabled by setting
`environment.ldso32 = null` or `environment.stub-ld.enable = false`.
Both combined fixes this error:
error: attribute 'i686-linux' missing
Portals are global so we can just link them globally.
There might, in theory, be some unexpected system-path contamination
(e.g. when a portal package installs its executables to `/bin`)
but I think the risk is relatively minor compared to the added complexity.
While at it, let’s point the environment variable to system-path.
That will allow changes to installed portals to apply without having to re-log in.
x-d-p only looks for portal definitions in one of two places:
- datadir (which we cannot install anything to, since Nix packages are immutable)
- when `XDG_DESKTOP_PORTAL_DIR` environment variable is set, the path specified therein
(meant for tests, disables looking for portal configuration anywhere else)
Let’s introduce our own `NIX_XDG_DESKTOP_PORTAL_DIR` environment variable
that will only control the portal definitions lookup.
We will not use it for searching for configuration
because it would require looking in the parent directory
and `XDG_CONFIG_DIRS` variable is sufficient for us.
After 4b128008c5 it took me a while in a
test setup to find out why `root` didn't have the password anymore I
declared in my config.
Because of that I got reminded how the order of preference works for the
password options:
hashedPassword > password > hashedPasswordFile
If the user is new, initialPassword & initialHashedPassword are also
relevant. Also, the override is silent in contrast to any other
conflicting definition in NixOS.
To make this less surprising I decided to warn in such a case -
assertions would probably break too much that technically works as
intended.
Also removed the `initialHashedPassword` for `root`. This would cause a
warning whenever you set something in your own config and a `!` is added
automatically by `users-groups.pl`.
`systemd-sysusers` also seems to implement these precedence rules, so
having the warning for that case also seems useful.
- Use `options = {` instead of repeating `options` for every option
- Change the description of "net.core.rmem_max" slightly to match the kernel documentation
This replaces the krb5 module's options with RFC 42-style krb5.settings
option, while greatly simplifying the code and fixing a few bugs,
namely:
- #243068 krb5: Configuration silently gets ignored when set by
multiple modules
- not being able to use mkIf etc. inside subattributes of
krb5.libdefaults, e.g. krb5.libdefaults.default_realm = mkIf ...
See #144575.
Closes#243068.

we previously defined a custom type for `boot.kernel.sysctl."net.core.rmem_max"`
to resolve to the highest value set. this patch adds the same behavior to
`"net.core.wmem_max"`.
as this changes the type from a string to an integer, which is a breaking
change this patch also includes a release note and updates the transmission
module to use a number for `wmem_max`.
If we include users with unset groups, we get this very confusing
message, with invalid Nix code:
- The following users have a primary group that is undefined: qyliss
Hint: Add this to your NixOS configuration:
users.groups. = {};
We don't need to include such users in this check, since they'll be
caught anyway by this one:
- users.users.qyliss.group is unset. This used to default to
nogroup, but this is unsafe. For example you can create a group
for this user with:
users.users.qyliss.group = "qyliss";
users.groups.qyliss = {};
we just need the script, borrowed from environment.noXLibs
On my system this reduced the closure size by ~100MB
