  • Doesn’t the motorola phone have a settings screen for defining what the button does? For Samsung they like to re-purpose the power button.

    First of all, it brought up bixby. I turned it back to powering off the phone and disabled bixby.

    Then, with the new update they re-assigned the power button to gemini. So, I turned it back to powering off the phone and disabled gemini too.

    However, the problem these days is that I’m never completely sure I’ve turned off all of the AI nonsense on my phone.




  • Linux secure boot was a little weird last I checked. The kernel and modules don’t need to be secure boot signed. Most distros can use shim to pass secure boot and then take over the secure boot process.

    There are dkms kernel modules that are user compiled. These are signed using a machine owner key. So the machine owner could for sure compile their own malicious version and still be in a secure boot context.





  • OK so it’s fairly simple. You need to install the acl package (or whatever equivalent package contains getfacl/setfacl. Then you can use that to dump the data from an entire structure into a file (I also then bzip that). Then I backup all installed packages to help with a restore too.

    So the script looks like:

    #!/bin/bash
    cd /etc
    /usr/bin/getfacl -R . | /usr/bin/bzip2 -9 >PERMISSION_BACKUP.bz2
    chmod 600 PERMISSION_BACKUP.bz2
    cd /home
    /usr/bin/getfacl -R . | /usr/bin/bzip2 -9 >PERMISSION_BACKUP.bz2
    chmod 600 PERMISSION_BACKUP.bz2
    cd /root
    /usr/bin/getfacl -R . | /usr/bin/bzip2 -9 >PERMISSION_BACKUP.bz2
    chmod 600 PERMISSION_BACKUP.bz2
    cd /var
    /usr/bin/getfacl -R . | /usr/bin/bzip2 -9 >PERMISSION_BACKUP.bz2
    chmod 600 PERMISSION_BACKUP.bz2
    /usr/bin/apt list --installed | /usr/bin/bzip2 -9 >/root/INSTALLED-PACKAGES.bz2
    chmod 600 /root/INSTALLED-PACKAGES.bz2
    

    To restore you change to the folder the backup was taken from, unbzip the file (or uncompress live via pipe) and use setfacl --restore=<file>
