This makes me ask a few questions..

1) Why is ash the default? At least on UNIX systems that use "true" sh -- usually just /bin/bash in /bin/sh compatibility mode -- I can understand THAT because plain sh is, well... "traditional". :-)  Bash2 seems closer to most expectations; ash doesn't seem to add any value. 
2) How would a user know they are defaulting to ash? 
	a) The first place I would look is /etc/password for my default, which "clearly" states /bin/bash (at least for me it does). 
	b) Next I would ls -l on /bin/whatever to see if it is a symbolic link to something else. Even on NTFS, /bin/sh or /usr/bin/sh do not appear to be links.
