Merely switching to the console should do the job.
Linux provides an ioctl, VT_WAITACTIVE, to let a
program wait for a tty to become activated.

With the SAK solution, child death will notify the
parent process. The parent can then start getty.

I have about 2000 glyphs, but Linux currently can't handle
more than 256 (or 512 w/o bright backgrounds) because the
internal representation is still tied to VGA.

I thus trim my font to the regular PC character set. If the
kernel were fixed though, you could have 2000 glyphs.

The 256-glyph file is attached.

The project has failed if it doesn't create new UNIX die hards.
These will be the people who drive the future economy.
