On my ubuntu system here (heron), /bin/sh is a symlink to  /bin/dash,
for which there is a man page that starts off explaining that it is a
project to strictly implement the POSIX definition of sh.

It's a bit weird that you'd  get  /bin/sh  when  you  login,  if  the
/etc/passwd file has bash as your login shell.  Is this really what's
going on?  I'd think that the login program would run  your  declared
shell, but it sounds like this isn't true any more.
