Adding

# Required-Start: $local_fs

to the test script makes it work as intended, my bad:

# cat /root/test.txt
Tue Apr 9 15:34:39 CEST 2024 stop
Tue Apr 9 15:34:56 CEST 2024 start

But still I don't understand why nftables does not load the ruleset on boot with:

# Default-Start: S

but it does with:

# Default-Start: 2 3 4 5

Are you sure the init script with this LSB header causes the script to run at boot, rather than merely giving the impression that it does?

### BEGIN INIT INFO
# Provides:          nftables
# Required-Start:    $local_fs $network $remote_fs $syslog
# Required-Stop:     $local_fs $remote_fs $syslog
# Default-Start:     S	
# Default-Stop:      0 6
# Short-Description: nftables firewall service
# Description:       nftables firewall system service
### END INIT INFO

For reasons unknown, none of my Debians run the script at boot with

# Default-Start: S

I assume the issue may also exist on Devuan. This seems to be a general problem with all init scripts under Debian whose "Default-Start" tag is set to "S". For example, I created the test file

  /etc/init.d/test.sh

with the following content:

  #!/bin/bash

  ### BEGIN INIT INFO
  # Provides:          test
  # Required-Start:
  # Required-Stop:
  # Should-Start:
  # Default-Start:     S
  # Default-Stop:      0 1 6
  # Short-Description: Test
  # Description: Test
  ### END INIT INFO

  echo $(date) "$@" >>/root/test.txt

and I enabled it with:

  update-rc.d test.sh defaults

which results in these, and only these, rc symlinks being created:

  rc0.d/K01test.sh
  rc1.d/K01test.sh
  rc6.d/K01test.sh
  rcS.d/S01test.sh

After rebooting the system from an empty '/root/test.txt' file, the contents of
this file become:

  Tue Apr 9 01:26:50 CEST 2024 stop

in which only one line is logged, corresponding to the time when I issued the
reboot command, with no follow-up lines after the reboot.
