[config-package-dev] config-package-dev doesn't like 'set -o pipefail'?

[Patrick Schleizer]

Hi!

I isolated an issue. When setting 'set -o pipefail' in the postinst
script, the 'undisplace' action is no longer working.

In function 'check_undisplace_unlink' the following code doesn't match.

    if LC_ALL=C dpkg-divert --list "$package" | \
	grep -xFq "diversion of $file to $theirfile by $package"; then
	undisplace_unlink "$prefix" "$suffix"
    fi

i.e. 'undisplace_unlink' is never called.

Does this sound plausible to you or should I provide further information
on how to reproduce this?

Is this something you would consider a bug, worth fixing or is your
answer "just don't use pipefail"?

Cheers,
Patrick
