It is not the prettiest thing but it is a very clever solution.
Perhaps it could be mitigated with an addendum that makes it optional,
and to be used only when strictly needed, after all moving files
within the same package is fine, it's only the combination of moving
location _and_ package that causes problems. In other words:
- every package is forcefully canonicalized as soon as trixie is open
for business
- the moratorium on moving files from bin/ sbin/ lib/ _and_ to other
packages at the same time is maintained from bookworm till trixie, and
will lifted after trixie ships, and applies implicitly to all the
~2000 binary pkgs that are affected by the above
- the moratorium can be bypassed by a maintainer if and only if the
appropriate conflicts/replaces/diverts as discussed in this thread are
put in place and left there for as long as needed (TBD whether this
means for trixie's cycle or for trixie+1)
In practice, I suspect that out of ~2000 packages shipping bin/ sbin/
lib*/, only a small fraction would end up needing to further move
files out to other packages, so the divert dance requirement can be
restricted only to those. This way impact is minimized, required
testing is smaller, and we get in the final state on day one of trixie
dev cycle.
Moving files between packages already requires busywork anyway, so a
bit more won't hurt that much, especially if we figure out a way to
provide the functionality with a dh addon or such to do the heavy
lifting.
