[NBLUG/talk] fighting Ubuntu, and the "source" bash command

[Barry Stump]

One thing that might help to know is that newer versions of Ubuntu use
dash for many scripts (anything referencing /bin/sh in fact) while
retaining bash for your login.  I don't remember when this change
first occurred, but I think it was later than 6.06.
