Bug#1038416: possible fix

thanks


Hi all,

Here we go, there is a better solution. 

It is possible to install and enable a third unit file such as:

+++ /etc/systemd/system/proftpd-run.service:

[Unit]
Description=ProFTPD FTP Server in standalone/socket mode
OnFailure=proftpd.socket
OnSuccess=proftpd.service

[Service]
Type=oneshot
Environment=CONFIG_FILE=/etc/proftpd/proftpd.conf
EnvironmentFile=-/etc/default/proftpd
ExecStart=/usr/bin/grep -iqE '^[[:space:]]*ServerType[[:space:]]+standalone$' $CONFIG_FILE
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Here one can enable only this service and install only the other ones.

systemctl disable proftpd.service
systemctl disable proftpd.socket
systemctl enable --now proftpd-run.service

do the task.

I would add this solution to git and prepare an ad hoc p-u for bookworm, but 
I'd prefer having a go from the release team, before that.

- cheers
