[PLUG] How is it logged...

No not a program, the osst driver dumped errors to the console
instead of a log file.  The same thing at least used to 
happen sometimes with floppy drives too.  It would be nice 
if the error logging of various drivers could be linked to 
user defined facilities under menuconfig so that stuff can 
be broken out more without extra processing.  Just
getting driver messages including that error 
recovery is occuring  off the console I'm using 
is what I'm after.  Maybe I can redirect stderr
next time I run taper.  There are lines in osst.c
that say kern_xxx suggesting the logging is supposed
to go to syslog.  Why then does it go to the 
console when a bad sot in a tape is found?  If var 
were not mounted I'd understand, but this isn't the 
case.  If it's the driver writer's fault that's,
very annoying programming style to have a driver
print to stderr.
