A list of features mandatory for the Linux builder. The builder will

this list. All mandatory features are automatically included in

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.

The protocol used for communicating with the build machine. Use

`ssh-ng` if your remote builder and your local Nix version support that
|

improved protocol.
|

|

Use `null` when trying to change the special localhost builder without a

protocol which is for example used by hydra.
