io:format calls in mnesia

[Rick Pettit]

While working with a coworker we noticed that the mnesia sources are littered
with io:format/1 and io:format/2 calls. This explains a problem we had starting
nodes (which used mnesia) from Solaris inittab without redirecting stdout to
some file or /dev/null (i.e. we believe Solaris sent a SIGPIPE in response
to attempt to write to a non-existent stdout).

Was the use of io:format/1 and io:format/2 (vs. error_logger routines, etc)
intentional?
