Rewrite ‘with pkgs.lib’ -> ‘with lib’ Using pkgs.lib on the spine of module evaluation is problematic because the pkgs argument depends on the result of module evaluation. To prevent an infinite recursion, pkgs and some of the modules are evaluated twice, which is inefficient. Using ‘with lib’ prevents this problem. 2014-04-14 14:26:48 +00:00			`{ config, lib, pkgs, ... }:`
* Modularise vfat support. Also add fsck.vfat to the initrd. This prevents errors when booting from VFAT (e.g. an ISO image converted using unetbootin). svn path=/nixos/trunk/; revision=32956 2012-03-09 16:17:37 +00:00

nixos/filesystems: make supportedFilesystems an attrset this lets us disable filesystem explicitly, as is required by e.g. the zfs-less installer images. currently that specifically is only easily possible by adding an overlay that stubs out `zfs`, with the obvious side-effect of also removing tooling that could run without the kernel module loaded. 2024-02-18 22:35:17 +00:00			`inInitrd = config.boot.initrd.supportedFilesystems.vfat or false;`

nixos/filesystems: Make most simple filesystems compatible with systemd This includes disabling some features in the initrd by default, this is only done when the new initrd is used. Namely, ext and bcache are disabled by default. bcache gets an own enable option while ext is detected like any other filesystem. 2022-04-16 19:46:32 +00:00			`boot.initrd.extraUtilsCommands = mkIf (inInitrd && !config.boot.initrd.systemd.enable)`
