[Pkg-shadow-devel] Bug#317264: login: Current su breaks pbuilder

[Junichi Uekawa]

Hi,

Apart from being unhappy about a core component of 
Debian dramatically changing at all; to answer your
question:

The implications of needing quoting means that previous 
quoting conventions will need to change.

Applications which used to pass quoted text to su, and 
needs to quote differently now need to change dramatically.

  su username command A $B "C $D"
used to work, but it will now need to be 
  su username -c "command A \"$B\" \"C $D\""
and specific semantics of how the contents of $B and $D is expanded is 
going to change.


regards,
