Hi, I just noticed that when purging an installed kernel, the
/etc/kernel/postrm.d/systemd-boot hook runs twice; here's an example:

    # apt purge linux-image-5.17.0-1-amd64
    Reading package lists... Done
    Building dependency tree... Done
    Reading state information... Done
    The following packages will be REMOVED:
      linux-image-5.17.0-1-amd64*
    0 upgraded, 0 newly installed, 1 to remove and 37 not upgraded.
    After this operation, 454 MB disk space will be freed.
    Do you want to continue? [Y/n]

I don't personally know well enough how these scripts are invoked and I can't
propose a solution, but the scripts suggested by Andre and Sam in bug #826045
seem to not have this issue.
