I don't, but really, I am not sure I ought tobe spending much
more time on an arcane reading of this corner case.
The issue, apparently, is that under policy, some shell can
come up with all kinds of shadowing of things like debconf. I
suggest that if brought before the TC, the TC shall decide that is a
bug in the shell. Policy is not supposed to be written to specify
all kinds of silly and deliberate malice on the part of shell
authors.

O, good grief. This is not Law 101. This is the technical
policy all kinds of non native developers must read, understand, and
follow; arcane corner cases and increasingly complex language to
resolve corner cases just makes policy asinine, turgid, obfuscated,
and abstruse.
