Generally, most production systems don't like to be restarted unnecessarily.
I was wondering if it's possible to change kernel logging without a restart?
Say, I connected a serial cable to the server, but kernel was not booted
with anything like console=ttyS0,19200 in its command line. So anything
produced by the kernel will not show up on ttyS0.
Can I still somehow make the kernel to log to ttyS0, without restarting
it (I can make syslog do it, but let's assume the syslog crashed and I'm
mostly interested in catching a kernel oops/panic etc.)?
