On the latest debian version the /etc/rc.local file is deprecated, but we can add it back using systemd for those scripts or applications that still depend on it.

Note that this is not the correct way of doing it, and you should probably create a service for your script or application, but if you don’t want to spend the time just yet to migrate everything over you can simple add the rc.local file back into Debian 10.

First we need to create a service file:


$> cat /etc/systemd/system/rc-local.service

[Unit]
Description=/etc/rc.local
ConditionPathExists=/etc/rc.local

[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99

[Install]
WantedBy=multi-user.target


Then we create the rc.local file again


$> cat /etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0


Then we make rc.local executable and enable and start the new service.


#> chmod +x /etc/rc.local
#> systemctl enable rc-local
#> systemctl start rc-local
#> systemctl status rc-local


You can now add what you want back into the rc.local file, of course this is not the ‘correct’ way of doing, best would be to add a service for your scripts/programs in systemd where possible.
