Package: dpkg
Version: 1.13.25
Severity: grave
If the old version of the package contains symlink, and the new version
tries to save a directory into the same place, then an upgrade won't be
correct.
example:
nb:[/root/temp]# ls
nb:[/root/temp]# export LANG=en_US.UTF-8
nb:[/root/temp]# mkdir 1 2 2/test-dir
nb:[/root/temp]# ln -s /bin 1/test-dir
nb:[/root/temp]# for i in 1 2; do cd $i && tar -czf ../packet-$i.tgz . && cd
..; done
nb:[/root/temp]# alien -kd packet-1.tgz && alien -kd packet-2.tgz
