Hi, I'd like to extend power-management.nix with an aggressive setting:
aggressive = mkOption {
default = false;
description =
''
Whether to enable aggressive power management features. An
area for experimentation. Please send feedback about this
to the list.
'';
};
and:
config = mkIf cfg.enable {
...
powerManagement.cpuFreqGovernor = "ondemand";
} // cfg.aggressive ? {
...
powerManagement.scsiLinkPolicy = "min_power";
} : {};
Now for one the syntax is incorrect and for another
powerManagement.cpuFreqGovernor would not be set, as powerManagement
will be overriden with the value from the second attribute set.
Is there a way to recursively merge attribute sets, so that
cpuFreqGovernor and scsiLinkPolicy would be set in powerManagement?
How can I achieve the conditional merge?
I tried:
config = mkIf cfg.enable ({
...
} // (if cfg.aggressive then {
...
} else { }));
--> infinite recursion
regards
florian
