# dumb-init is a minimal init / PID-1 signal proxy (compiled C, /sbin),
# carried with a wasm32-hwjs patch: the user lane does not service
# rt_sigtimedwait, so the recipe replaces upstream's sigwait loop with
# sigaction handlers + blocking waitpid, and defaults setsid mode off
# (the setsid tty hand-off collapses the console pty on this runtime;
# DUMB_INIT_SETSID=1 restores it). Run every case BARE -- do NOT wrap in
# `timeout`: its SIGALRM+wait path hangs on this runtime (the
# brintos/linux#9 signal breakage), which wedges even working tools.

# A signal-killed child must end the supervision loop. Upstream semantics
# are 128+signum; this platform's ash reports the TERM self-kill as a
# plain exit today, so accept either -- what this case guards is the
# supervision loop ending at all (the unpatched tool hung forever here).
