 ```
-
-## Chain NixOS in same disk with other systems
-
-To install NixOS on a partition along another system which controls the GRUB,
-first disable the grub device, so the GRUB is not installed in the disk by
-NixOS (only the /boot files will be generated):
-
-```
-boot.loader.grub.device = "nodev";
-```
-
-Then add the following entry to the old GRUB configuration:
-
-```
-menuentry 'NixOS' {
-        insmod chain
-        search --no-floppy --label nixos --set root
-        configfile /boot/grub/grub.cfg
-}
-```
-
-The partition with NixOS must have the label "nixos" for it to be found. New
-system configuration entries will be stored in the GRUB configuration managed
-by NixOS, so there is no need to change the old GRUB settings.

 Much like the silent flight of an owl at night, these nodes are configured to
 minimize the system noise and let programs run undisturbed. The list of nodes is
 `owl[1-2]` and are available for jobs with SLURM.
-
-The contents of the nix store of the hut node is made available in the owl nodes
-when a job is running. This allows jobs to access the same paths that are on hut
-to load dependencies.
-
-For now, only the hut node can be used to build new derivations so that they
-appear in the compute nodes. This applies to the `nix build`, `nix develop` and
-`nix shell` commands.
