Package: bird2
Severity: important
Version: 2.0.4-1
Hi,
When bird2 supersedes bird it does not properly take over the
configuration file /etc/bird/bird.conf in ucf. When the bird package is
purged, it results in the following situation:
# aptitude search '~c'
c bird - Internet Routing Daemon
# apt policy bird bird2
bird:
Installed: (none)
Candidate: 1.6.8-2.1

Purging configuration files for bird (1.6.6-1+deb10u1) ...
ucfr: Association belongs to bird2, not bird
ucfr: Aborting
dpkg: error processing package bird (--purge):
installed bird package post-removal script subprocess returned error
exit status 5
Errors were encountered while processing:
bird
E: Sub-process /usr/bin/dpkg returned an error code (1)
But the postrm for bird has already removed the configuration file:
# ls /etc/bird/
envvars local.conf
so now bird2 fails to start and the configuration is lost (yay backups).
