Bug#1039434: zookeeper: ships sysv-init script without systemd unit

[bluca at debian.org]

Package: zookeeper
Severity: important
User: bluca at debian.org
Usertags: missing-systemd-service

Dear Maintainer(s),

zookeeper has been flagged by Lintian as shipping a sysv-init script
without a corresponding systemd unit file. The default init system in
Debian is systemd, and so far this worked because a transitional
sysv-init-to-unit generator was shipped by systemd. This is in the
process of being deprecated and will be removed by the time Trixie
ships, so the remaining packages that ship init scripts without
systemd units will stop working.

There are various advantages to using native units, for example the
legacy generator cannot tell the different between a oneshot service
and a long running daemon. Also, sanboxing and security features
become available for services. For more information, consult the
systemd documentation:
https://www.freedesktop.org/software/systemd/man/systemd.unit.html

You can find the Lintian warning here:

In case this is a false positive, please add a Lintian override to
silence it and then close this bug.

Thanks!
