Hi Daniel,
I am sorry to tell you that the brittle /usr-move mitigations broke
again. Holger made me aware of a bookworm to trixie upgrade failure. It
can easily be reproduced.

zutils.preinst from trixie is faced with what looks like a fresh install
as /bin/zcat is not diverted, but gzip's diversion of /usr/bin/zcat
still exists, as gzip has not been configured.
My vague memory is that this used to work differently and note that apt
switched to the 3.0 solver fairly recently.
If apt were to actually configure gzip after removing zutils,
gzip.postinst would be removing the .usr-is-merged diversions and we
were not having this problem.
If apt were to upgrade zutils rather than removing and installing it,
the zutils.preinst script were noticing the old diversion and correctly
handling the protective diversions installed by gzip.
What it is not prepared to handle is being removed and then reinstalled
in that window between gzip being unpacked and configured where those
protective diversions exist.
I will provide a patch, but not immediately, because I've gotten this
wrong so many times already.
Helmut
