 Worth understanding, because it catches out anything written as a daemon:
 `montauk::print` is `SYS_PRINT`, which writes the kernel *terminal*, not the
 kernel *log*. Only in-kernel `KernelLogStream` writes raise `g_kernelLogDepth`,

+and only those append to the ring buffer `SYS_LOG` reads -- so daemon output
 never shows up in `klog`. On top of that, `Sys_Print` returns early once
 `g_suppressKernelLog` is set, which the desktop does at startup, so the output is
 discarded outright from then on. `init` spawns services with `spawn` rather than
