Debian changed to dash in large part to make sure that there
weren't bashisms in the RC scripts. (There were. They got
fixed.) The other reasons were to reduce required dependencies
and decrease boot times.

Having bash as the system shell rarely causes problems. Having
scripts that need bash but don't declare it explicitly is the
problem.
