set +e before executing scripts in pre/postinst scripts?

[Martin Schulze <joey@finlandia.Infodrom.North.DE>]

Hi,

Due to bash bug #23857, the installation of several daemon packages
will fail if `set -a' or `set -o allexport' has been used in the root
shell that executes dpkg.

Francesco Potorti` proposed to to make the pre- and post- installation
scripts set "+e" before executing a subscript.

Can this please be discussed here and perhaps made policy?

For the moment I'll implement it this way.

To reproduce this try:

set -a
set +a
dpkg -i .../sysklogd_1.3-26_i386.deb; echo $?

Regards,

	Joey
