Is there anything ISPConfig might be changing/using that influences grub? I am running fresh ubuntu 24.04 install on a vps with zfs rpool and after I run my install script update-grub suddenly does not find any entries anymore (and thus does not boot). Any suggestion is appreciated.
Thank you. I think it has to do with terminal settings or something. I managed to figure out where it was going wrong and filed the bug: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/2102163
