First install (migration from the SysV layout):
- The postinst ran daemon-reload before stopping koha-common.service, so
the name already resolved to the new native unit and the stop was a
no-op; the daemon(1)-supervised starman/zebrasrv/workers survived and
kept plack.sock and the Zebra sockets. The init script itself is gone
by then (koha-common's rm_conffile) and the koha-* helpers already
dispatch to systemd, so neither can be used either. Kill the legacy
koha-common.service cgroup (the generated unit has KillMode=process,
a plain stop leaves the supervisors alive), sweep remaining pid files,
and wait for them to exit, all before daemon-reload.
- Nothing ever started the new units, and koha-common.service was never
enabled, so a migrated host came back with every instance stopped and
"systemctl restart koha-common" doing nothing. Enable both koha.target
and koha-common.service and start them through deb-systemd-invoke.
- koha-plack@ was enabled for every instance including CGI-only ones,
and koha-indexer@ regardless of USE_INDEXER_DAEMON. Use
"koha-list --enabled --plack" and /etc/default/koha-common like the
init script did.
- Drop the "systemctl disable koha-common.service" that targeted our
own compat unit.
Upgrade: deb-systemd-invoke takes unit names, not glob patterns, so
enumerate the active koha-*@*.service units before try-restarting them.
Removal: the prerm only did a daemon-reload, leaving every daemon
running with its unit file deleted, so swapping to koha-sysv started a
second copy of each. Stop koha-common.service and koha.target on
remove; a new postrm removes the enablement symlinks on purge and
reloads the manager.
