Systemd: gandi-postboot startup error

[alorence]

Hi,

Currently, gandi-postboot init script run /usr/bin/python2 /gandi/init at startup (or /usr/bin/python if python2 doesn't exists).
On my server, the script /gandi/init contains exactly this code:

#!/bin/sh

echo "I'm a useless script most of the times"

Obviously, it's a Shell script, so its execution by Python interpreter is not possible. As a result, the systemd unit "gandi-postboot" don't run and the service remains in "failed" state:

# systemctl status gandi-postboot.service

I'm on Debian 8 with kernel 3.12.70:

Hi,
Thanks!

The "useless" script is the default we use when we did not provision an init script on the node. Were you testing this on our new datacenter ?

Also, the postboot script should not assume it'll be provided with a python script, we should probably fix that.

Hello !

The server with these scripts has been created 2 or 3 years ago and is located at Bissen. I assume it uses the GandiV4 platform.

While debugging #6, i noticed this same problem:

Still seeing this problem any my Debian 9 system.

Also seems to affect bootstrap.d/01-config_swap which also assumes /gandi/init is a python script if it is executable.

Still seeing the same problem on my Debian 11 system.

root@auckland:~# dpkg --list | grep gandi

BTW I get a lot of other errors (notably on /etc/udev/rules.d/86-gandi.rules):
