Error messages are normally printed to stderr or piped to a system logging 
daemon, which would make attempting to pipe the output to the null device 
seem somewhat counter-productive. As the messages would have been written to 
a file or output to the console by default, the null device would instead 
destroy them, accomplishing the opposite of what you intended.

For reference, you can pipe the information from one program to another using:
	program_one | program_two

With multiple requirements, you can also construct more advanced command 
structures by piping information to several programs in series:
	program_one -args | program_two -args "param" | program_three 2> error.log

Although I can't see how that level of system instability would be possible 
under the circumstances, your next option would be to instruct your boot 
loader to boot using runlevel 1, which may be able to bypass some of the 
startup errors and allow you to repair the configuration and software. You'll 
need to google your specific boot loader on that procedure, as they vary 
depending on which piece of software you're using.

It wouldn't have been the first time, having been doing development, system 
administration and customer support for several years, although I don't 
believe I can be blamed in this case. Please let me know if you have any 
questions which I can help you with, and good luck!
