.SH EXAMPLE
.nf
/sbin/\fBsleeping-getty\fP \fI15\fP /sbin/got tty\fI15\fP TERM=linux
/sbin/\fBsleeping-getty\fP \fI16\fP /sbin/got tty\fI16\fP TERM=linux
/sbin/\fBsleeping-getty\fP \fI20\fP /sbin/agetty -8 -s 38400 tty\fI20\fP linux
.fi
.SH RATIONALE
It is nice to have a score or two of TTY:s available. However,
starting them, can require some unnecessary CPU time and will
was memory until they are actually used. This becomes extra
important on resource contained machines.
