heise+ | Ubuntus Linux-Bootloader abgespeckt: Weniger Funktionen für mehr Sicherheit
Die Ubuntu-Entwickler planen, den Bootloader Grub zu beschneiden: Keine Grafiken mehr, kein LVM, kein RAID, kein Btrfs. Das soll Angriffswege reduzieren.

PSA regarding a change in how Secure Boot will work in Fedora soon. The change isn't urgent, but it is something you should take a look at.
If you have any questions about this, please ask in our forum. 🙏

Reminder: Bleibt entspannt bezüglich der ablaufenden Zertifikate für #UEFI #SecureBoot, eure bestehenden #Linux-Installationen sollten alle weiterhin booten.
Vereinfacht gesagt stört sich nämlich kaum eine Firmware daran, wenn der Boot-Loader eine Signatur eines mittlerweile abgelaufenen Zertifikats trägt – anders als ein Webbrowser, der in so einem Fall den Besuch einer Webseite blockiert.
Im Detail gibt es naturgemäß doch einige Tücken, die euch über kurz oder lang ereilen könnten. Siehe dazu folgende Texte:

Also #FLOSS does work!
That's why #Cyberfascism like "#AgeVerification", #CensorBoot aka. "#SecureBoot" and "#DeviceAttestation" is being shoved down, with #criminalization of those that refuse to comply!And yes, that doesn't exclude the need to abolish the #GAFAMs and actually enforce existing laws!

Repeat after me:
"#DeviceAttestation" is just as much #Malware as #CensorBoot aka. "#SecureBoot" and "#KernelLevelAntiCheat / #ClientSideAntiCheat"…
Appeasement of #Cyberfascists that demandnit won't help!Only if #Consumers universally reject #Apps that demand this shit will we not get the #Enshittification of another #iOS on #Android…

Today on the joys of my new laptop: it seems the CMOS battery is death on arrival.
Which means when I keep the computer in a sleep state that drains battery to the point of it shutting down, I get the very strange experience of the BIOS going back to default settings, with Secure Boot being re-enabled and me being unable to boot because I got rid of Windows.
Strangely, all of the secure boot fields in the AMI (🤮) bios are greyed out, and randomly turning it off and back on, adding and removing admin (so BIOS access) and user (so PC booting permission) passwords and then removing them....
