Bug#1030024: systemd-cron: missing Breaks+Replaces: cruft-common (<< 0.9.44)

[Alexandre Detiste]

Hi,

Thank you so much.

This is deeply interesting.

The same bug might happen in the 495 other packages that
are candidate for using dh-cruft too (the one list in "rules/" in src:cruft).

I will try to fix this at once in dh-cruft instead of requiring
Break+Replaces everywhere.

Simplest option is to change the legacy /usr/lib/cruft/filters-unex/
API directory to something else for dh-cruft generated rules
and have cruft-ng consider both the old and new location.

Greetings,
