-* add VT tracking:
- - provide CK functionality
- - start getty only when actual vt switch happens (same model as
- socket on-demand activation). allocate the next free tty and
- start a getty there. this way, pressing alt-f[1-12] will switch
- through running X and getty sessions, and any unallocated
- activated tty will start a new getty. the hardcoding of
- getty[1-6] will entirely go away.
