debhelper treats debian/<package>.init as that package's init script, so
koha-sysv would have shipped /etc/init.d/koha-sysv (with generated
update-rc.d and invoke-rc.d handling) as well as the .install-copied
/etc/init.d/koha-common (with none). That meant two identical init
scripts, two generated units on systemd hosts, and on a fresh
non-systemd install the "update-rc.d koha-common disable" call in the
postinst aborting with "no runlevel symlinks to modify" because
nothing had ever created them.
Rename the script to debian/koha-sysv.koha-common.init and run
dh_installinit --name=koha-common for koha-sysv. debhelper now installs
it as /etc/init.d/koha-common, registers the rc.d links, starts it on
install, restarts it on upgrade, stops it on removal and removes the
links on purge, which is exactly what the old koha-common package did.
The hand-written prerm/postrm and the Bug 18250 disable/enable dance
(a one-off link reshuffle from 2017 that is a no-op under
dependency-based boot) are dropped in favour of the generated code.
