<title>Description</title>

<para>When run as system instance systemd reads the

configuration file <filename>system.conf</filename>,

otherwise <filename>user.conf</filename>. These

configuration files contain a few settings controlling

basic manager operations.</para>

<listitem><para>Configures the initial

CPU affinity for the init

<varlistentry>

<term><varname>MountAuto=yes</varname></term>

<term><varname>SwapAuto=yes</varname></term>

<listitem><para>Configures whether

systemd should automatically activate

all swap or mounts listed in

<filename>/etc/fstab</filename>, or

whether this job is left to some other

system script.</para></listitem>

<varlistentry>

<term><varname>DefaultControllers=cpu</varname></term>

<listitem><para>Configures in which

cgroup controller hierarchies to

create per-service cgroups

automatically, in addition to the

name=systemd named hierarchy. Defaults

to 'cpu'. Takes a space separated list

of controller names. Pass an empty

string to ensure that systemd does not

touch any hierarchies but its

own.</para></listitem>

</varlistentry>

<varlistentry>

<term><varname>JoinControllers=cpu,cpuacct</varname></term>

<listitem><para>Configures controllers

that shall be mounted in a single

hierarchy. By default systemd will

mount all controllers which are

enabled in the kernel in individual

hierachies, with the exception of

those listed in this setting. Takes a

space separated list of comma

separated controller names, in order

to allow multiple joined

hierarchies. Defaults to

'cpu,cpuacct'. Pass an empty string to

ensure that systemd mounts all

controllers in separate

hierarchies.</para></listitem>
