The packages jack-example-tools and jackd1 cannot normally be
coinstalled as they require incompatible versions of jack. However, they
can still be concurrently unpacked.

mmdebstrap --verbose --variant=apt '' /dev/null 'deb http://deb.debian.org/debian trixie main' --include=jackd1 --chrooted-customize-hook='apt-get download jack-example-tools && dpkg --auto-deconfigure --unpack *.deb'

This results in an error.

Selecting previously unselected package jack-example-tools.

Unpacking jack-example-tools (4-2) ...
dpkg: error processing archive jack-example-tools_4-2_amd64.deb (--unpack):
trying to overwrite '/usr/share/man/man1/jack_simple_client.1.gz', which is also in package jackd1 (1:0.126.0-2+b3)
Errors were encountered while processing:
jack-example-tools_4-2_amd64.deb

Given that these provide overlapping functionality, I guess a Conflicts relation would be appropriate here. I expect that jack1 is more likely
to be removed at some point and therefore recommend that it is jackd1
who carries the relation despite jack-example-tools having arrived
later.
