Bug#1085162: s390-tools: move aliased files from / to /usr (DEP17)

Source: s390-tools
Version: 2.16.0-2.1
Severity: serious
User: [email protected]
Usertags: dep17m2

This package is part of the /usr-move (DEP17) transition, because it
contains files in aliased locations and should have those files moved to
the corresponding /usr location. The goal of this move is eliminating
bugs arising from aliasing, such as file loss during package upgrades.


You may add dh-sequence-movetousr to Build-Depends to perform the move.
The main advantage of this method is the low effort and it just works when
backporting to bookworm.  However, it is more of a stop-gap measure as
eventually the installation procedure should refer to the files that are
actually used for installation. This often means updating debian/*.install
files but also changing flags passed to a configure script or similar
measures.
In case you do not anticipate your package being uploaded to
bookworm-backports, please prefer a manual move, but generally prefer moving
over delaying any further.

After having done this move, please keep in mind that the relevant
changes need to be reverted for bookworm-backports, with these
exceptions:
 * dh-sequence-movetousr and dh_movetousr cancel themselves.
 * dh_installsystemd and dh_installudev revert to the aliased location.
 * The pkg-config variables systemdsystemunitdir in systemd.pc and
   udevdir in udev.pc reverts to aliased.

Please keep in mind that restructuring changes may introduce problems
after moving. A change is considered restructuring if formerly aliased
files formerly owned by one package are later to be owned by a package
with a different name. Such uploads should be done to experimental and
quarantine for three days before moving to unstable. This way, automatic
analysis (https://salsa.debian.org/helmutg/dumat) can detect problems
and file bugs. Such bugs shall include support for resolving the
problems.
