Hi,
The openblas packages mentioned above install an empty directory
/usr/lib/<triplet>/pkgconfig. If a different package containing
/lib/<triplet>/pkgconfig were to be removed, dpkg could be lead to think
that /lib/<triplet>/pkgconfig is not owned by any package anymore and
thus delete it. Doing so would delete /usr/lib/<triplet>/pkgconfig due
to the aliasing introduced by /usr-merge. This is only a problem if the
removal happens after unpacking and before running postinst, because the
alternatives prevent dpkg from removing the directory. I therefore
suggest creating the directory in postinst. This mitigation can be
dropped after trixie is released, because we expect that no package will
install files into aliased directories in trixie and later.
Helmut
