Where? I do not see this in policy.
______________________________________________________________________
The standard shell interpreter ``/bin/sh'' may be a symbolic link to
any POSIX compatible shell. Thus, shell scripts specifying ``/bin/sh''
as interpreter may only use POSIX features. If a script requires
non-POSIX features from the shell interpreter, the appropriate shell
has to be specified in the first line of the script (e.g.,
``#!/bin/bash'') and the package has to depend on the package
providing the shell (unless the shell package is marked `Essential',
e.g., in the case of bash).
Restrict your script to POSIX features when possible so that it may
use `/bin/sh' as its interpreter. If your script works with ash, it's
probably POSIX compliant, but if you are in doubt, use `/bin/bash'.
______________________________________________________________________
Where does it say I *have* to use /bin/sh? It tells me to
stick to POSIX features so it _could_ be used with /bin/sh. Nothhing
says I have to use /bin/sh. In fact, it sauys, if in doubt, use
/bin/bash. I shall do so, since I do not want to worry about whether
my changes tomorrow shall fail when /bin/sh is not bash!
I have no idea why you are on this crusade; but leave my
packages out of the /bin/sh politics. Or change policy.

Who cares?
I code with /bin/bash. It is essential. Unless you can point
me to the line in policy where it says theat one must use /bin/sh as
the shell; this is not going to change.
I am again closing this bug. Change policy if you want to see
this changed.
