 +===== Reset HP OfficeJet Pro 8600 Plus =====
 +<code>
 +My printer is a N911n, and I have not found a consistent way to reset it.
 +I did get the Home, Back, Home, Home to work possibly one time a couple months ago, so not sure if the Oct 31st firmware changed something,
 +as I have not been able to do any kind of reset.  
 +(tried the Back x 4-5 times as well at boot up, but nothing happens, after power off/unplugging for 1-10 mins).

 +==== Umzug Rootfs ====
 +  * Boot von USB-Stick (grml)

 +  * cp -a /mnt/old_rootfs /mnt/btrfs-rootsubvol
 +  * grml-chroot /mnt/btrfs-rootsubvol /bin/bash
 +    * grub-install /dev/sdd
 +    * grub-install /dev/sde
 +    * fstab anpassen - nur die wichtigen einträge aktiv lassen um bootfehler zu vermeiden
 +    * initrd (u kernel) neubauen mit dracut
