+ .Pp
+ As the major number allocated for emulation of SVR4 devices may vary between
+ .Nx
+ platforms, the SVR4_MAKEDEV script utilizes the
+ .Xr uname 1
+ command to determine the architecture the devices nodes are being created for;
+ this can be overridden by setting the
+ .Ev MACHINE
+ environment variable accordingly.
 .El
 .Pp
 An alternative method is to mount a whole SVR4 partition in /emul/svr4
