0d7cd66652 broke validation for hashes with options
such as those generated with `mkpasswd --method=sha-512 --rounds=1000000`:
$6$rounds=1000000$xpzZ6Rfg873gZnDY$RxS7lpVnohfDrrKG3lt9UFHED1KoiPGzH7zQv/HzwalZepo/IfFtxw05ap25duEJSKYhC14.Fn9eXszEpWVtF.
This fixes it.
A change made in #166308 added `networking.resolvconf.package` to the
`environment.systemPackages` list, so it is installed as part of the
system image. However it does so unconditionally, meaning that even if
the `config.networking.resolvconf.enable` is set to false the package
listed in the `networking.resolvconf.package` would still be intalled.
This change makes it so the package installation will depend on the
status of the `config.networking.resolvconf.enable` option instead.
The single option tries to do too much work, which just ends up confusing people.
So:
- don't force the console font, the kernel can figure this out as of #210205
- don't force the systemd-boot mode, it's an awkward mode that's not supported
on most things and will break flicker-free boot
- add a separate option for the xorg cursor scaling trick and move it under the xorg namespace
- add a general `fonts.optimizeForVeryHighDPI` option that explicitly says what it does
- alias the old option to that
- don't set any of those automatically in nixos-generate-config
Updates the warnings message for statefully set up passwords, now that
weak algorithms have been removed from our libxcrypt package.
Additionall we now add proper validation for hashing schemes used in
`hashedPassword`.
Neither will prevent a rebuiild, but instead issue a warning, that this
requires immediate remediation, or else users will be unable to login.
Reuses the crypt scheme ids as provided by the libxcrypt package.
Without this change, users that have both `initialHashedPassword` and
`hashedPassword` set will have `initialHashedPassword` take precedence,
but only for the first time `/etc/passwd` is generated. After that,
`hashedPassword` takes precedence. This is surprising behavior as it
would generally be expected for `hashedPassword` to win if both are set.
This wouldn't be a noticeable problem (and an assert could just be made
instead) if the users-groups module did not default the
`root.intialHashedPassword` value to `!`, to prevent login by default.
That means that users who set `root.hashedPassword` and use an ephemeral
rootfs (i.e. `/etc/passwd` is created every boot) are not able to log in
to the root account by default, unless they switch to a new generation
during the same boot (i.e. `/etc/passwd` already exists and
`hashedPassword` is used instead of `initialHashedPassword`) or they set
`root.initialHashedPassword = null` (which is unintuitive and seems
redundant).
From SuperSandro2000's post-merge review of the PR adding this,
nixos/no-x-libs: add qtbase. Sandro added a comment about this after I had
already merged it; self'/super' previously masked the top level self/super.
