+ used as an effective way to disable
+ invocation of non-native binaries
+ system-wide, for example to prohibit
+ execution of 32-bit x86 binaries on
+ 64-bit x86-64 systems. This option
+ operates system-wide, and acts

+ setting of unit files, see
+ <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>

+ the empty list, in which case no
+ filtering of system calls based on
+ architecture is applied. Known
+ architecture identifiers are
+ <literal>x86</literal>,
+ <literal>x86-64</literal>,
+ <literal>x32</literal>,
+ <literal>arm</literal> and the special
+ identifier
+ <literal>native</literal>. The latter
+ implicitly maps to the native
+ architecture of the system (or more
+ specifically, the architecture the
+ system manager was compiled for). Set
+ this setting to
+ <literal>native</literal> to prohibit
+ execution of any non-native
+ binaries. When a binary executes a
+ system call of an architecture that is
+ not listed in this setting, it will be
+ immediately terminated with the SIGSYS
