deb: use symlink to install systemd-sysusers
Using dh_installsysusers(1):
FILES
debian/package.sysusers If the file exists, it will be installed as /usr/lib/sysusers.d/package.conf.

With this PR, there's a (dangling) symlink added, similar to the existing ones;
ls -la deb/common/

Something isn't working with this, but perhaps I'm either using the wrong name for the symlink, or we need to invoke something else?
I tried to install the package in a container;
apt-get -y update && apt-get -y install ca-certificates curl
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
chmod a+r /etc/apt/keyrings/docker.asc
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
apt-get -y update
apt install ./docker-ce_0.0.0~20250520085713.af09051-1~debian.13~trixie_arm64.deb
After that, I don't see a file in /usr/lib/sysusers.d/
ls /usr/lib/sysusers.d/
basic.conf dbus.conf systemd-journal.conf systemd-network.conf systemd-timesync.conf
Also looked it it was perhaps installed in another location;
docker diff upbeat_euclid | grep sysusers
A /usr/share/man/man5/sysusers.d.5.gz
A /usr/share/man/man8/systemd-sysusers.8.gz
A /usr/share/man/man8/systemd-sysusers.service.8.gz
A /usr/bin/systemd-sysusers
A /usr/lib/sysusers.d
A /usr/lib/sysusers.d/basic.conf
A /usr/lib/sysusers.d/dbus.conf
A /usr/lib/sysusers.d/systemd-journal.conf
A /usr/lib/sysusers.d/systemd-network.conf
A /usr/lib/sysusers.d/systemd-timesync.conf
A /usr/lib/systemd/system/systemd-sysusers.service

oh! We probably need something like these to set --name=docker! https://github.com/docker/docker-ce-packaging/blob/fc7702737d2551f403208f44e25da6f210d017a1/deb/common/rules#L136-L142
Ah! It's because we're still on 12?? https://github.com/docker/docker-ce-packaging/blob/fc7702737d2551f403208f44e25da6f210d017a1/deb/common/control#L10
