DBX is the method used by UEFI firmware to block execution of known-bad and known-vulnerable UEFI binaries when running with Secure Boot enabled. Apt does not know show anything here as the DBX is not a package, it's a lower-level update to firmware.

Why is it masked? I don't know the full story either, but I did note that there's also an /etc/init.d/nfs-common script (a rather substantial one, at that).

Why is it masked? My /guess/ is that it's because systemd doesn't need it: there's a systemd service for each component (imapd, gssd, … … ). However, if you don't run systemd, then all those services are started by an init.d script called nfs-common, turned on and off with /etc/default/. Cheers, David.

udev not on-demand-loading modules with custom kernel
Hi all. I need help getting module on-demand-loading working with a custom kernel. Currently I'm running Debian 11 for x86_64 on a Chromebook in developer mode directly via Coreboot/Depthcharge. Not having UEFI or classical BIOS boot code means that the default Debian kernel doesn't work, right? So I'm using a kernel from the chromiumOS project (ChromeOS 5.10) with a custom config. I do need a patched kernel anyways as there's no UEFI/ACPI but a special Chromebook embedded controller for all those fancy sensors and a like. The system is working fine, including wifi, rotation sensors, graphics and so on except the on demand kernel module loading doesn't work. Running "edevadm monitor" I do get many UEVENTs when plugging in an usb stick, for example. The event device system itself does work. But trying to mount the filesystem doesn't work as no vfat module gets loaded (as an example). Likewise adding rules via iptables doesn't work, as the netfilter modules are missing. I have to manually load the nf* modules and _then_ I'm able to use iptables. I can load all those modules by hand via modprobe, but autoloading via kernel/udev doesn't work. Running "depmod -a" was fine. The files /lib/modules/[kernelversions]/modules.* seem(!) also to be ok. "find /sys/ -name "uevent" | wc -l" seems also fine with more than a thousand results. When I try for example mounting the fat system without having the vfat module ready, on my standard desktop system "udevadm monitor" shows events and mount succeeds. But on the Chromebook with custom kernel there's no such event shown and mount fails with: "mount: /mnt: unknown filesystem type 'vfat'." After "modprobe vfat" everything is fine and mount succeeds. Indeed the udev events do show when manually running modprobe. systemd-udevd.service is running. The files in /run/udev/* seem to be the same on the desktop (where everything is fine) and Chromebook (not working). Does anyone has an idea how to solve this? Feel free to ask me further details of the system. I don't know how the module autoloading works so I have no idea which additional information is useful. regards hede

(don't want to .. experiment with this) Since none of us can reproduce your archive, only you are in a position to test that. Doing it in a subdirectory of /tmp or /var/tmp ought to be harmless enough. You can just nuke that subdirectory when you're done with it.

But you could create a small ext filesystem in a file, mount it and make experiments with it. From the view of the Linux kernel the expectable unpacking activities of tar should not be too exotic. I am quite sure that attempts to link a file to itself have happened in the last 25+ years: $ ln x x ln: failed to create hard link ‘x’: File exists > the "machine" is a VM, pre-installed by Google, and it has more mounts > than dog has fleas :-) (but '/' says is on btrfs) I know that flea effect from ZFS on Solaris.

firmware: secure boot dbx with software-center but not apt?
Hello, i get a message from 'gnome-software' to update my firmware: " update configuration secure boot dbx: Version 217: This updates the dbx to the latest release from Microsoft which adds insecure versions of grub and shim to the list of forbidden signatures due to multiple discovered security updates. " but on the contrary apt update/upgrade does not show anything to be updated so what is this? and why doesn't apt show anything? S.
Information et amélioration a propos de LMDE 5
Bonjour, Toujours, je tiens à remercier toute l'équipe qui contribue au développement de linux mint version debian (paquets). J'apprécie énormément cette distribution. Elle est à la fois, stable, légère, simple d'utilisation pour un débutant linux, rapide en fonctionnement. Surtout, continuez svp a développer cette version debian linux mint. Elle est génial. J'aime bien aussi le fait de pouvoir créer très simplement des lanceurs de programme depuis le clic droit sur le bureau. Une fenêtre s'ouvre et on a plus qu'à choisir le programme et de cocher ou non le choix de lancer le terminal ou pas. Cette fonction est génial également. Elle n'existe pas sur vos '' concurrents'' comme Ubuntu et compagnie. Je reste donc sur mint debian. Maintenant, je trouve dommage qu'il n'existe pas de documents PDF ou de manuel en ligne qui explique en détail comment on procède à installer Linux mint debian sur un disque en choisissant l'option ''autre chose '', pour faire concrètement un pationnement de disque dur adéquat et opérationnel pour faire l'installation. Comment partionner, la taille, etc ... pour faire une partition efi, swap , home . Bref du concret. J'ai réussi à installer LMDE sur un disque dur externe, car j'ai une machine windaube avec un disque aux partions non modifiable, non accessible, en mbr. Donc pas compatible avec le nouveau bios et le format gpt. Bref, une notice aurait aider et simplifier. A part ceci, nickel le LMDE. La version debian 11 pure en revanche est compliqué pour un débutant, concernant l'installation encore une fois (choix mode installation ''autre chose'' ) et les pilotes a installer ou a télécharger manuellement etc. C'est pour cela que je préfère LMDE. Continuez donc svp a développer et à améliorer cette version. Mille merci encore. Amicalement
