# console-login — exec ttymon on /dev/console with a properly quoted prompt.
#
# Wrapping ttymon in a script (instead of inlining in exec.start) sidesteps
# zyginit's str.split-on-space tokenizer, which doesn't honor shell quotes.
# Inline the ttymon invocation here where the shell DOES quote correctly,
# then exec so ttymon becomes the supervisor's direct child.

# Write a LOGIN_PROCESS utmpx entry for the PID that's about to become
# ttymon (this script's PID, since we use `exec` below). ttymon's
# getty_account() (tmutmp.c) updates an existing entry — it does not
# create one — so without this, login(1) walks utmpx, finds nothing
# matching its PID, and exits with "No utmpx entry. You must exec
# login from the lowest level shell."

# the full xterm spec.
