Let's rephrase it that way: If you debug a remote system without
being able to tear it down it's quite useful to increase system verbosity
and at the same time increase the log buffers (without affecting the overall
system) to gather more information then would be possible in the default
configuration.

I did not argue about how the patchset looks like, just about the functionality
being useful under certain circumstances (for me it is useful).

This might not always be possible. If it is, of course using remote syslog
would be preferred.
