Yes.

No.  Most Linux systems do by default, but few require that it be
maintained that way.  Some even have ash as /bin/sh.

JC's question was not about /bin/sh (he knows that may not be bash).
It was about /bin/bash.  And as far as I know, all distros do use
/bin/bash (if they have bash installed at all), but I've only looked
at a small handful of the distros out there.

If you limit yourself to the features available in bourne shell.  JC
wants to use bash-specific extensions.

I think that using #!/bin/bash is probably reasonable.  The number of
distros that don't have that is certainly small, maybe nil.  And if
there are any, they must be used to it causing problems.

But I'm sure JC would like to hear that from someone who has looked at
more distros than I have.  :-)
