bootctl: ignore the bootloader boot entries

kreijack · kreijack · commit 9914d89b5162 · 2022-01-18T19:32:35.000+01:00
When bootctl lists the boot entries, considers also the ones
returned by systemd-boot (via the efi LoaderEntries variable),
created at boot time.

Unfortunately this list may became incorrect if (e.g.) the user remove a
kernel package.

This patch changes this behaviour, so bootctl ignores some the
boot entries returned by systemd-boot.

In any case, bootctl still considers the 'auto-xxx' boot entries
listed below:

  Boot entrie name                 Title
  -----------------------------    ------------------------------
  auto-osx                         macOS boot loader
  auto-windows                     Windows Boot Manager
  auto-efi-shell                   EFI Shell
  auto-efi-default                 EFI Default Loader
  auto-reboot-to-firmware-setup    Reboot Into Firmware Interface

The other entries that systemd-boot synthetizes (e.g. the ones loaded from
/efi/loader/entries/&lt;uuid&gt;) can be synthetized by bootctl too, so no
information is lost.
