Note that because of the Bashisms whatever address was negotiated is not
assigned.  This applies at least to IPv6, and if the bashisms interfere
in IPv4 then it also interferes there.

This means the essential function of the application does not operate,
and the bug should potentially be a higher severity level.  (I'm setting
to High because it "renders essential features or functionality of the
application or dependencies broken or ineffective" - which is defined as
a "High" criterion in the Bug Importance page of the bugsquad
documentation)

** Changed in: isc-dhcp (Ubuntu)

Status in isc-dhcp package in Ubuntu:
  Confirmed

Bug description:

  Shebang line needs to be /bin/bash, or the script needs to be
  rewritten.
