A list of features mandatory for the Linux builder. The builder will
be ignored for derivations that don't require all features in
this list. All mandatory features are automatically included in
{var}`supportedFeatures`.
This sets the corresponding `nix.buildMachines.*.mandatoryFeatures` option.

This option specifies the maximum number of jobs to run on the Linux builder at once.
The number of concurrent jobs the Linux builder machine supports. The
build machine will enforce its own limits, but this allows hydra
to schedule better since there is no work-stealing between build
machines.
This sets the corresponding `nix.buildMachines.*.maxJobs` option.
