Hi Joe, nice to see encryption getting promoted. The instructions setting up hibernation on the swapfile will not work though. Beginning where the wiki says … ```auto sudo blkid -s UUID -o value /dev/mapper/vg0-lvroot ``` returns the UUID of the root volume. This will not work because the standard encrypted install you describe will not produce any logical volumes; so there won’t be any volume group vg0 and no lvroot. Instead of /dev/mapper/vg0-lvroot you should address the ext4 filesystem. ---

I actually have all my machines encrypted, not just mobile devices so I would suggest renaming the Wiki to just “Encrypted installation”. ---

I did a quick check in VirtualBox. Actually /etc/default/grub has everything set up correctly out of the box. The only thing that needs to be added is the swapfile offset. I propose changing the wiki swapfile part to the following … * * * **Make a swapfile** If you want to use hibernation, then you must add **swap** because the content of the **RAM** will be written to the swap partition/file. This also means that the swap size should be **at least** the size of **RAM**. The following commands will produce a swapfile the size of **8GB**. copy and paste them one after the other inside terminal and give your **root password**. If you want more or less swap change **8G** to what you want to use as swap. ```auto sudo fallocate -l 8G /swapfile ``` ```auto sudo chmod 600 /swapfile ``` ```auto sudo mkswap /swapfile ``` ```auto sudo swapon /swapfile ``` To check … ```auto swapon --show ``` Edit **/etc/fstab** to enable the swapfile after reboot ```auto sudo leafpad /etc/fstab ``` Add the following line … ```auto /swapfile none swap defaults,pri=-2 0 0 ``` Save and exit. **Activate hibernation** ```auto sudo filefrag -v /swapfile | awk '{if($1=="0:"){print $4}}' ``` returns the swapfile offset. For example `997376..` , which means 997376. ```auto sudo leafpad /etc/default/grub ``` **Change** to the following; remember to **use your offset**. It will first look like this: (\*\*\* are the long snake of UUID numbers) > GRUB\_CMDLINE\_LINUX\_DEFAULT=“quiet cryptdevice=UUID=_ **:luks-** _ root=/dev/mapper/luks-\*\*\* resume=/dev/mapper/luks-\*\*\* loglevel=3” Add `resume_offset=`\*\*\*\*\* to the end of this line (after loglevel=3). Insert offset number we got from the command before here. Save and exit Add `resume` to /etc/mkinitcpio.conf, do this now … ```auto sudo leafpad /etc/mkinitcpio.conf ``` Change the HOOKS=… line by adding `resume` . HOOKS=“base udev autodetect modconf block keyboard keymap encrypt lvm2 resume filesystems fsck” Save and exit rebuild kernel images and grub.cfg: EFI and Bios systems: `sudo mkinitcpio -p linux` `sudo grub-mkconfig -o /boot/grub/grub.cfg` ---

i will add your changes to the wiki now, thanks again for the help! We are working on a solution to let users directly comment on wiki entries for an easy contribution to it. ---

> This can’t work because the kernel and initramfs is on the encrypted partition and not accessible until the drive is unlocked ([https://superuser.com/questions/974833/change-the-keyboard-layout-of-grub-in-stage-1](https://superuser.com/questions/974833/change-the-keyboard-layout-of-grub-in-stage-1)) this sounds legit… and creating a core image to get this working is so… arch-alike 😆 thinking of doing this automaticly for the install process… is a nightmare ---

the other option would be to have a seperate boot partition, what is also secure enaugh in my opinion, there is no personal data stored…
