It was a system speed enhancement. Much of the bootup speed gain was due to switching to dash. bash is slow. bash adhere's to sh standards is just fine except that it won't flag extensions, so you can still end up with bashisms in your shell script. I've never had any issues w/bash. I write shell scripts that run in bash2, bash3, bash4, ash, dash, ksh88, ksh93, mksh, SunOS sh, Tru64 sh, AIX sh, HP-UX sh.
