Then, it shall execv(3) to GETTY_COMMAND, + with GETTY_COMMAND and all following arguments as the command line + arguments. + + Note that this program ways on VT:s, not TTY:s.

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. + +SEE ALSO + getty(8), mingetty(8), agetty(8), got(8), vtchs(1) + |
