Is the serial console support not appropriate / acceptable?
Well, I brought this up myself in another message. I would indeed
consider it adequate ifa blind sys admin could get access to the boot
messages via the serial console. But I'd like to know with absolute
certainty that the proposed change to the linux kernel wouldn't also
effect a serial console.
I am not a kernel developer but it doesn't make sense to me that
something that would force speakup out of kernel space wouldln't also
force a serial console out of kernel space. In which case, how is it
going to get boot messages? As a technical issue, what's the difference
between speakup and a serial console? Why is one so bad and the other
one okay?
This is another example of some questions I asked on the kernel
developers list and didn't get satisfactory answers. But I suspect that
the answer is that the serial console was once in common use in the
linux/unix community and speakup is not. Serial consoles are familiar
and speakup is not.
