1633 WARNING: This field has a non-traditional meaning for BusyBox init!
1634 The id field is used by BusyBox init to specify the controlling tty for
1635 the specified process to run on. The contents of this field are
1636 appended to "/dev/" and used as-is. There is no need for this field to
1637 be unique, although if it isn't you may have strange results. If this
1638 field is left blank, it is completely ignored. Also note that if
1639 BusyBox detects that a serial console is in use, then all entries
1640 containing non-empty id fields will _not_ be run. BusyBox init does
1641 nothing with utmp. We don't need no stinkin' utmp.

1683 process it displays the line "Please press Enter to activate this
1684 console." and then waits for the user to press enter before starting
1685 the specified process.

1365 WARNING: This field has a non-traditional
1366 meaning for BusyBox init! The id field is used
1367 by BusyBox init to specify the controlling tty
1368 for the specified process to run on. The
1369 contents of this field are appended to "/dev/"
1370 and used as-is. There is no need for this field
1371 to be unique, although if it isn't you may have
1372 strange results. If this field is left blank,
1373 it is completely ignored. Also note that if
1374 BusyBox detects that a serial console is in use,
1375 then all entries containing non-empty id fields
1376 will _not_ be run. BusyBox init does nothing
1377 with utmp. We don't need no stinkin' utmp.

1402 enter before starting the specified process.
