With Debian Bookworm systemd-boot is a separate binary-package, instead of part of the main systemd package. Since it's not installed by default, Debian-upstream has added hook-scripts to the package, which manage kernel copying to the esp (kernel-install).
The hookscripts print a warning if the ESP is not mounted at $SYSTEMD_ESP_PATH or /boot/efi, /efi or /boot - through `bootctl is-installed --quiet` [0,1]. This patch adds a function, which disables the hookscripts from upstream if /etc/kernel/proxmox-boot-uuids is present. It adds an explanation as marker and 'exit 0' on top of the script, so that users know why the scripts were touched (e.g. when a new systemd-boot hookscript version from upstream asks what to do with the local modifications) While editing shell-script hooks from other packages is quite brittle it still seems like the best option, to support most use-cases (including users, who don't use proxmox-boot-tool, but want to manually install systemd-boot). Alternatives considered: * dpkg-divert for all hookscripts - sadly the Debian policy manual warns against this * adding Replaces: systemd-boot to d/control - afaict this would need systemd-boot to also declare this for proxmox-kernel-helper [3] Tested on 2 VMs installed with the 8.0 ISO (once with legacy once with uefi boot) [0] https://github.com/systemd/systemd/blob/8a38b62f37189b071a30f208530ce5dc278e521e/src/shared/find-esp.c#L503 [1] https://github.com/systemd/systemd/blob/8a38b62f37189b071a30f208530ce5dc278e521e/src/boot/bootctl.c#L90 [2] https://www.debian.org/doc/debian-policy/ap-pkg-diversions.html [3] https://www.debian.org/doc/debian-policy/ch-relationships.html Reported-by: Aaron Lauterer <a.laute...@proxmox.com> Signed-off-by: Stoiko Ivanov <s.iva...@proxmox.com> --- src/proxmox-boot/zz-proxmox-boot | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) diff --git a/src/proxmox-boot/zz-proxmox-boot b/src/proxmox-boot/zz-proxmox-boot index c6c708c..c72f9ef 100755 --- a/src/proxmox-boot/zz-proxmox-boot +++ b/src/proxmox-boot/zz-proxmox-boot @@ -191,6 +191,27 @@ remove_old_kernels_legacy() { } +disable_systemd_boot_hook() { + + if [ ! -f "${ESP_LIST}" ]; then + return + fi + + marker="# This hookfile has been disabled by proxmox-boot-tool" + for hookfile in \ + "/etc/initramfs/post-update.d/systemd-boot" \ + "/etc/kernel/postinst.d/zz-systemd-boot" \ + "/etc/kernel/postrm.d/zz-systemd-boot" ; \ + do + grep -q "$marker" "$hookfile" && continue + warn " Disabling upstream hook $hookfile" + printf "#!/bin/sh\n\n%s\nexit 0\n" "$marker" > "$hookfile.pbt.tmp" + cat "$hookfile" >> "$hookfile.pbt.tmp" + mv "$hookfile.pbt.tmp" "$hookfile" + done + +} + set -- $DEB_MAINT_PARAMS mode="${1#\'}" mode="${mode%\'}" @@ -203,12 +224,14 @@ case $0:$mode in reexec_in_mountns "$@" BOOT_KVERS="$(boot_kernel_list "$@")" update_esps + disable_systemd_boot_hook ;; */postrm.d/*:|*/postrm.d/*:remove) reexec_in_mountns "$@" # no newly installed kernel BOOT_KVERS="$(boot_kernel_list)" update_esps + disable_systemd_boot_hook ;; esac -- 2.30.2 _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
