# ptyd registers the "pty" scheme and signals readiness by sending its scheme
# cap fd back to init (redox_scheme ready_sync_scheme / ready_with_fd), so init
# must receive that fd via call_ro(FD) — i.e. type must be {scheme="pty"}, NOT
# "notify". With "notify" init waits for a readiness byte ptyd never sends and
# blocks forever at ptyd, before the console/login stack. See ptyd/src/main.rs.
